Morning, sir. Welcome. If you will open the technical information menu on the opening page there is an excellent series on disassembly/assembly. Without wanting to be prejudiced (I'm a shooter guy, not a collector)I recommend you determine what you want. Is it for collection or for shooting purposes? If for collection then the matching/pitting/overall condition is extremely relevant. If not and you have possible intentions of reworking the gun then
go for value. Pictures are very useful. The price of shooters is steadily increasing and collector guns are increasing at sometimes double the rate of shooters. A shooter, unless a very rare gun, will never be a collector. But you can make a collector into a shooter simply by removing one part or getting out a bottle of cold blue. An excellently reworked gun will have a value over a non reworked gun if its a shooter, but not higher than a collection gun in not as good condition. Hope this helps.
