Following the loss of Lancaster KB718 VR-J on 4/5 July 1944, KB762 became the new VR-J. On the night of July 15/16 KB762 made its maiden operational sortie. From the first sortie to more than 23 sorties later F/L George R.H. Peck DFC was the pilot of VR-J.
F/L Peck and his crew continued to fly operations on Jiggs up until September 17th.the end of the crews Tour. For this reason it would seem probable that Peck and his crew named KB762 "Jiggs" .
Jiggs was a cartoon character from the series Maggie and Jiggs, also known as Bringing Up Father. A character who was it seems always in trouble

KB762 completed 72 ops. before it was lost in an accident with the collapse of the undercarriage on April 23 1945 at Middleton St. George.

S/L Clifford Black's Memory of the Night, As Told Many Years Later

My bomb aimer, McKinnon, had done his job and always sat on the bench with the navigator who was seated just behind me. He stood up to stretch his legs and asked if he could look out the cockpit window to see this B17.
After a while, we finally decided that had to be one of ours that really got screwed up so we figured that they might want to follow me home in case their instruments were out, so I gave them the benefit of the doubt. As the old Lancaster is faster than a Fortress, I figured I would just decrease speed a little bit to give him a break. As I slowed down, the B17 increased speed and went up 75 yards ahead of me then suddenly dipped down and went under my nose and opened fire from its rear gun. Flight Lieutenant Black immediately climbed hard to port as the tracers came up but was unable to avoid some of the 0.50 calibre bullets that slammed into the Lancaster's nose, one shell injuring one of the Lancaster crew! Bomb aimer McKinnon didn't say a word or yell he had been hit. My navigator said Mac had been hit and was down. In the meantime, the B17 had vanished. We had to get to an emergency hospital because Mac's foot was almost shot off and he might bleed to death. We carried these big shock things [crash pads] in the aircraft you could pull down off the wall.
We put the pad around his foot and pulled these long strings to create pressure to stop the bleeding. There was an emergency base at Woodbridge so I opened up the old Lancaster and fifteen miles out from the base, I radioed the tower, told them I had an emergency with a wounded crew man who needed emergency treatment. As soon as the wheels touched down and the aircraft came to a stop, an ambulance and a crash truck were already standing by. It was amazing how fast they whisked Mac off for treatment. We bedded down that night at Woodbridge which was about an hour from our base and in the morning we visited Mac. He was asleep and minus his right foot. Really sad but at least he survived. That was the last time I saw Mac.
