Hello, molly. A relative who was a Lancaster pilot went down in flames over Germany on his 18th mission towards the end of the war, managed to bale out and after capture spent about a year in Stalag Luft 1. He did his RAF training in Canada, and his chute was made by Irvin, Canada. He lost his pin some 5 years ago, and I contacted Irvin, Canada, who, although it was an European operation, could not do enough and supplied a pin together with the nicest letter. I sent an e-mail for you to a name that I had in Canada, and received a reply from a different name indicating Letchworth. However, I have since discovered that Irvin UK is listed as a dormant company with the address Irvin Aerospace Ltd, Bettws Road, Llangeinor, Bridgend, mid Glamorgan, CF32 8R. I have not yet tracked down the Caterpillar Club, which surely must still exist, but I have some enquiries out and will let you know if they bear fruit.
