Thread: What is this?

Sorry for the lack of contact, been a bit chaotic with one thing and another. Here's a photo of all the bits, the sizing dies are all H&I, whatever that means, and there are 277,325, 225, 313, 258, 244, 358, and 309 diameter, as well as a top punch, and gas check seater. I don't know what any of these are, so I'm just assuming the labels are correct. @Tommy and @40mm are you guys still keen? Which bits are you wanting and how much would you offer?
Cheers, Tom
