Start individual threads here in C&R section. Have lots of pics for each firearm. I bet you get great info from our members.
For some of your more esoteric pieces, maybe contact these folks:

IMO - There are MANY people here that have a ton more knowledge on specific firearm platforms, than the average gun store employee that has a general knowledge across many platforms.
Your first (and easiest) course of action is to take pics and submit here. If you don’t feel you get enough info, then go to the next step. Whatever you decide that will be
Agree. Especially with the more esoteric stuff. Probably wouldn't satisfy an insurance company as an appraisal though.
I was thinking of one large continuous thread. You could do one gun a week. After all, its only a small 30 gun collection.
I've bought a number of C&R firearms form Atlantic Guns over the decades, and the owners have been in the game for generations. They've consolidated in Rockville now, which is a little inconvenient for DC residents. I'd trust them for appraisals, but I don't know whether they offer the service. Can't hurt to ask.
