Hi Daryl; I believe it's a 12 gau. probably 21/2 inch but haven't got that far into my "inspection".
the bore is like new so I think I'll "refurbish" it overtime - just another project - as if I needed one. A few parts missing but nothing serious, will try to find a parts gun first.

It's an interesting action due to the fact that not only the bolt handle but a small lug up front is used in the lock up. The stock is very English style, short fore-end and PoW grip.

Will take pics and foreward them to you if you wish? All take care --- John
