Peace Pipe - S2-E5
Continuity mistake: When Vince finds the liquor bottle in the drunk driver's car, he says that the driver has a cut, but doesn't think he feels it, and in the next overhead shot we see Johnny and Roy (at the left of the screen) walking away from the car with the drunk driver between them. However, in the next shot the drunk is still in the car, then in the next shot we see them at the front corner of Engine 51 in the background, but then he's back in the car again.
Continuity mistake: When DeSoto joins Gage at the kitchen table they discuss Gage's bright idea of rodeos. In all the shots facing DeSoto his hands are clasped together with the coffee cup on the table, but in all the shots facing his partner, he's holding the cup of coffee. The magazine ends up under DeSoto's arms between shots as well.
Continuity mistake: After treating the girl who had a soda pop bottle explode in her face, when John and Roy are carrying the stretcher out the door, they're facing the stretcher and each other in the interior shot, but in the exterior shot John has turned around, with his back facing Roy while carrying the stretcher.
Continuity mistake: While the children from the bus accident are being lowered on 43's snorkel, Roy and Johnny are in the bus with the nun. Then even though quite some time has passed, by the time Roy and John are ready to free her from the wreck, it cuts to the shot of the same children still being lowered on the snorkel.
Continuity mistake: After Sister Barbara is brought to the ER, when Dixie tells Roy to get coffee with her, Dixie has long nails with light colored polish as usual, but when it cuts to the closeup of Dixie's hands getting coffee from the urn, the long nails are unpolished.
Continuity mistake: When Roy and Johnny are with the boy who is trapped on the crane, Johnny buckles the life belt around the boy's waist, and in the following shots the belt's direction flips around to the opposite way repeatedly. Note its stitched leather and tongue buckles.

Continuity mistake: When Johnny and Roy are with the elderly man in the burning house, the window is pushed up fully when Mike climbs the ladder in the exterior shot, but when Mike breaks the window with the axe, the window is halfway down in the interior shot.
Continuity mistake: When Gage sees Sheila in the hallway at Rampart while she's undercover, he stops her midway between treatment room three and four and they are standing face to face. In the wide shots of both of them and in Sheila's close-ups, she's standing right in front of the emergency fire hose glass cabinet, but in Gage's close-ups, he's standing directly in front of the door to treatment room four, farther up the hallway.
Continuity mistake: At the park, when the attendants load the mugger into the ambulance, and also when the ambulance backs up to Rampart's ER receiving, just as Squad 51 turns and starts backing up, the type of ambulance that parked is a station wagon, but in the next shot while Squad 51 is still backing up, that ambulance has suddenly become the truck type.
Continuity mistake: When Roy and Johnny are rescuing the elderly man from the burning house, in the interior shot Roy exits the window by placing his left leg out the window onto the ladder, but when it cuts to the exterior shot Roy has his right leg out the window on the ladder.
Continuity mistake: Just after the paramedics witness the purse snatching, when Johnny and Ed take off after the two purse snatchers, there are four cars parked at the curb in front of the squad, but just before Johnny leaps over the white picket fence, behind him we see that there are now six parked cars in front of the squad.
Continuity mistake: While Ed is in the field with John and Roy, it's the three of them sitting in Squad 51 when they're en route to their destinations, but in some shots of the moving squad Ed is not seated between them, such as when they respond to the cliff rescue. Additionally, after the purse snatching incident, when they head to Rampart for John's hand injury, only one person's in the squad as it backs up to receiving, even though it should be three.
Continuity mistake: When Ed chases after the possible OD into the car wash, Roy sits at the passenger side of Squad 51 to contact dispatch about the sheriff's ETA, but each time it cuts to the car wash employee the squad is empty behind him, even though Roy is still there in his closeups.
Continuity mistake: When Christy walks into Station 51's kitchen, the bag strap is on her shoulder, but close-up it is gone, only to be back next shot when she removes it a moment later.
Continuity mistake: The shaving foam on DeSoto's face changes between the face-on shots and the reflection shots, and in the reflection he shaved from cheek to chin, but in face-on shots only to the neck.
Continuity mistake: Gage and DeSoto arrive at the apartment complex, home to the guy trapped in the couch. They park the vehicle and walk on the gated balcony to the apartment. In the exterior shot, when they enter the doorway the inside wall to their left is bare and the corner of the balcony's iron gate is to the doorway's left. Next interior shot, now there is a large painting on that previously bare wall and the iron gate is directly in front of the door. When they leave, their vehicle is farther away, positioned differently.
Dinner Date - S2-E10
Continuity mistake: When the paramedics and the rest of the firemen gather round the failed pacemaker patient, their positions change and in DeSoto's close-ups the Captain isn't seen (for the camera angle's sake), although in other shots he's right beside Gage. As an aside, note when Captain Stanley first first gets off the engine and trips in the background.

Continuity mistake: When DeSoto and Gage are in the pool with the little girl whose arm is stuck in the drain, their shoes and pants are soaked. However, just after Gage gets off the Biophone, his shoes and pants are completely dry, and then when the pool has been mostly drained both DeSoto and Gage are dry.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

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.
