Other mistake: When John and Roy treat the 12 year old boy in anaphylactic shock, Early states, "Start IV D5W, 1 milligram epinephrin IV push," and John confirms the order. Then after giving Rampart a new set of vitals which are poor, Early orders, "Add 50 milligrams Benadryl IV push." But when John confirms that order he only says, "1 milligram epinephrine IV push," (which is the earlier order) and Early actually okays John's incorrect repeat of the order, even though John did not confirm the order of "50 milligrams Benadryl."
Other mistake: When Brackett tells Johnny and Roy to contact the animal shelter via the disaster net, Roy asks the Animal Control guys for their disaster call, and it's given as 3-9-9-7-7-1-1, but in the closeup Roy presses channel 8 then punches in 4-2-1-6-5-3-7 on the scanner. Additionally, this model Regency Monitoradio / Executive Scanner Receiver has 8 channels, so it would have been impossible to press 9, as was stated by Dave.
Other mistake: During the structure fire, when Engine 98 rolls up we can see the large red vinyl adhered to the top of the engine's cab. Then, when Truck 106 rolls up we see its company number 106 on the door, but in the overhead shot we can see the number 8 on the roof of the cab, not 106. This presumably means that the door has one of the prop dept's magnetic decals imprinted with 106, and the roof still shows the Truck company's real number.
Other mistake: After finding out about Valerie's three kids, when Johnny and Roy are sitting in the station's locker room at the start of their next shift, there are a few moments during this conversation where Kevin Tighe softly mouths some of Randolph Mantooth's lines as Johnny is speaking, particularly when Johnny says "Beautiful chic."
Other mistake: After the officer hands Les the tranquilizer gun, Les asks which way the tiger went and the officer responds, "Down that aisle," and we see both men, who are standing right beside the self-serve ice cream freezer, moving slowly towards the aisle in front of that ice cream freezer. The problem is that in the next shot, we see the large tiger coming from that exact area in front of the ice cream freezer, as he walks toward the camera on the other end of the aisle. This means that the Bengal tiger, Les, and the officer would have all been standing in the very same spot, at the same time.
Other mistake: When Dixie and Mr. Hart are on the elevator, we see the number five lit up on the panel above the door as they head down to the first floor in the ER, where they meet Johnny and the kids, who get on the elevator to head up to the fourth floor. The problem is that the ER is only a 2-storey building.
Other mistake: All the guys are sitting around the table in the day room discussing how smart kids are, and when the tones drop we hear the dispatcher say, "Squad 51 possible assault victim," yet all the guys from the engine company rush off and head to the rig in the apparatus bay, even though only Roy and John were called.
Other mistake: When Johnny brings the officer who was shot into the ER, as soon as he's loaded onto the gurney Carol takes his BP then tells Brackett his BP, but she also tells him that his pulse is 120, even though she never took his pulse. Additionally, when Morton places the blood vials on the tray and tells the nurse, "I want this sent to the lab STAT, type and cross match, and CBC and differentials STAT," due to the urgency of the situation, but the nurse doesn't leave, she just stands for the rest of the scene.

Other mistake: When Engine 51 and Squad 51 first roll in during the school fire, we see the burning building has a flat roof. After Johnny and Roy have rescued the unconscious boy from the classroom, there is a closeup of two firemen standing on a slanted, tiled roof with a hose, which is from episode 3x2, "The Old Engine", just before 17's Captain Harmell falls through the warehouse roof.
Other mistake: After the apartment house fire, the restored old engine is trashed by a hail of bricks. Later, when Roy and Johnny are talking about who won the first prize, The Old Engine in the back looks nothing like it did when it was wrecked on the street. Also, the shot of The Old Engine that's shown here, is actually the same footage shown in season 3, "The Old Engine", with the lighting dimmed to signify nighttime, when at the end of the episode Roy and Johnny decide to keep it. Note the exact same broken pieces of windshield, tires, hubcaps, dirt, shadows, everything.
Daisy's Pick Blind Date - S4-E7
Other mistake: When Squad 51 is dispatched to "man needs assistance", in the exterior shot as the squad rolls out of the apparatus bay we can see Engine 51 still inside the bay, but the real Station 127's engine is parked right beside the station house.
Other mistake: After Roy and Johnny leave Wild Bill's apartment because he faked his injury, there's an overhead exterior shot of what is supposed to be Rampart, but it's not actually Rampart. Throughout the entire run of this series there are numerous exterior shots of Rampart from every angle.
Other mistake: After Early carries Martha into treatment 3, and he and Brackett begin examining her, there's a nice exterior shot of what is supposed to be Rampart, only it's not actually Rampart, and we know this since throughout the show's run there are numerous exterior shots of Rampart from every angle.
It's How You Play the Game - S4-E19
Other mistake: After Chet says that he doesn't like when people expect too much of him, Squad 51 is dispatched to "man bit by an animal," and when Roy gets into the squad the highly reflective chrome spotlight has been sprayed with a dulling spray, to temporarily dull the surface.
Other mistake: After Station 51 is dispatched to the structure fire, just as Roy and Johnny start heading upstairs we see footage from 4x3, "Gossip," when Johnny brings the hose to the stairs at the chemical fire, but the line doesn't reach so he leaves the hose at the bottom step, and they continue up.
Camera Bug - S4-E10
Other mistake: While Roy and John are at 68's, Roy goes to the stove to see what Bob was cooking when he started having pain, and the closeup footage we see of the pot of bubbling chilli is the same as some of the footage of Chet's chilli in 4x1, "The Screenwriter," when 'Miss October' stops by the station.
Other mistake: During the rescue at the top of the open drawbridge, in the shots of Engine 2 we can see the red, vinyl material with the company number imprinted on it, adhered to the front of the engine.
Other mistake: During the surgery on Brackett's father, after the closeup of the anesthesiologist there is a closeup of the Bird's Mark 4 unit, then a closeup of the bellows housing showing inflation and deflation, but on the bellows unit it reads "Animal Anesthesia Ventilator" made by Bird.
Other mistake: When Station 51 is dispatched to 'man trapped in vehicle', we can see the real Station 127's vehicle is still parked inside the apparatus bay, near the rear bay door.
Daisy's Pick Blind Date - S4-E7
Other mistake: When dispatched to the fire in the theater, the companies called are Station 51, Engine 85, and Station 36, but at the scene of the fire we see Engine 9 roll up and also see firemen with 19 on their helmets. These are shots from previous episodes including 3x7, "Promotion", when Roy and John rescue the security guard at the structure fire.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.
Bishop73
Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
