Tinker,

I would also be interested in why you think it is a sleeve job or chamber job.

You are talking about the 7.65 Guild Gun ?

I think the reason it is cheap is a plain, boxlock action.
low end wood, Non ejector, funny calibre -
7.65 cal - which would make brass hard to find and
maybe too thin in the barrels to take out to 9mm.

Why spend $3500 on that when you can buy a new
SxS 9.3 x 74R for similar ?
