Might not be easy unless they come off a scrapper. I might be able to lay my hands on some as I was offered some rough guns by a Dealer recently to see if I wanted any to de-activate into wall pieces before he sent them for scrap. That is if they haven't already gone. However, I do have a pair of bar action locks that came of a Midland Gun Co. Farmer's model hammer gun. The gun was in superb condition but some idiot had left it leaning at the side of a vehicle and it got run over smashing the stock and bending the barrels like a banana. The only bits to survive were the locks which are still fully colour hardened. I removed them and put them on one side some years ago. Lagopus.....
