The model 63 was discontinued in '58, except for a small reissue during the 90's, and with Winchester itself now basicly out of business your chances of finding an original manual is probably quite slim. There is another option though, DBI Books, Inc. has a series of firearm dissasembly/assembly books on the market and Part lll covers rimfire rifles which includes, among many others, the M#63.
Depends on make and model- there were several, and all different. The most common were the Winchester 94, and the Marlin 336. You can download an owner's manual showing disassembly from the maker's website- or take it to a gunsmith.
First, determine which model Winchester 12 gauge you have. Then go to www.stevespages.com/page7b.htm and download the manual. For a more detailed set of disassembly instructions, go to the Gun Digest bookstore www.krausebooks.com/category/firearms_knives and buy the Gun Digest Assembly/Disassembly book on shotguns.
