I just bought a Flues made in late 1910, according to the chart I found. S.N. 216458. It has a broken firing pin, and the gunsmith doesn't have time to work on it for a month or two. In the meantime I want to refinish the wood. The finish is original-gummy, scratched, etc., but no cracks. My question is exactly how does the stock come off? It appears to have a stock bolt in about half the length of the stock from the back. Also two tang screws of course, and the screw under the lever. It still doesn't want to budge. What did I miss? I do not want to damage it. Also, the seller said it has 2 3/4" chambers. When I put a tape measure in to the front of the chambers to the back of the barrels it measures exactly 3" to the extractor cut, and 3 3/32 to the rear of the barrels. Would this be a 2 3/4" chamber? And if so, would it have been lengthened from new, or original? Obviously this is my first old double, but I own several newer ones that never presented these questions or challenges. I love the gun, how light it is and how it feels and swings, and want to shoot it a lot some day with reduced pressure shells. It seems to be in very good shape otherwise, and not overly abused. It is very tight, with no wiggle anywhere with the forearm off, and the lever is slightly right of center. Any information you guys would share with me would be greatly appreciated.
