Entirely up to you. If rare or collectable, it might cause loss of value.
Can't be answered without knowing who made it and the serial number. don't refinish it.
the stock is what you use to hold the weapon by.
Do it for the experience and keep the gun. <><><><> Today (25 August 2011) I checked wholesale price on very good condition 91/30s- they are $79.95. Refinishing a collector's gun reduces the value. There is not a high colelctor's value on these to start.
the tf11 only comes with a stock or it doesnt. you can not buy an extra stock for the gun.
About half or 2/3rds. But some people like their guns to look good, so if you plan to keep it... shoot it, refinish doesn't affect operation.
Laminate floor cannot be refinished. It will have to be replaced. Hardwood flooring can be refinished.
My guess is you will need to buy another gun just like it, and have spare parts. I have a 583.19 that was my Dad's first gun, circa 1950's, and his Dad and I refinished the stock in the 1980's. Either someone will carve one up for you, or you will need to buy a whole shotgun. Mine has a beautiful and in-tect red-rubber and black phenolic pad on the end, I consider this to be the hardest part to replace. If your stock is still essentially "there", have it correctly refinished by a smith. If it is missing all together, I think you are going to be in the market for a whole gun, maybe one with bad rust or mechanicals so you can made one good one out of two abused ones. If you are doing it just to sell, don't bother, sell your good mechanicals, the market for these is sentimental only, unless you have one of the European rifles.
It should. I have a real m4 stock on one of my guns at the moment. just make sure that the stock is compatible with your setup. different companies offer different set ups. the stock should fit it though
100-300 USD or so
Whomever is actually finishing the floor.
It's quite possibly a valuable gun, but you'll need to post more information about it to get an accurate answer. What caliber is it chambered for? (The information should be stamped on the side of the barrel) The length and shape of the barrel, and features like a "fancy" grade stock or saddle ring will have an effect on the price. Most importantly, is this gun in excellent condition because it was carefully packed away for all these years ...or because it's been refinished?
There are many types of finish. Your local library should have books on furniture/woodworking, etc..
