I was shooting with a friend last night who just got a 1970's Perazzi made for Ithaca single barrel Trap Gun. I think he said it was a TM-1 or TMX-1. He had just bought what he thought were the right chokes from Briley. When he tried to install them the thread wasn't quite right. He showed me the original choke that came out of the gun. It had only the letter G imprinted on the side no other markings. It is a thin wall choke tube. I have included a couple of pictures( not the best sorry) I hope someone can help.
