N.B. The nickname "Gentlemen From Hell" has only been used in connection with the Group since the 487th Bomb Group Association was formed in 1967. It was not an official wartime nickname. The "Gentlemen From Hell" patch was used by a very few members of the 487th Bomb Group at Alamogordo, New Mexico during training Jan–Mar 1944, and during the early days of operations at Lavenham, England. Most veterans of the 487th Bomb Group knew nothing about it during the war.
This looks like a postwar reproduction. Mr. Freeman probably obtained it from a 487th Bomb Group veteran after 1967. It definitely was not the insignia of the 487th Bomb Group. There was no official 487th Bomb Group insignia. Roger Freeman Collection
