Looking for an appraiser

[Karl Miller]

Hello Guys,
Here are a few pictures of my SBT. I was only able to post 5 images. It is a 12 gauge, with a 30" barrel, Case hardened. Bluebook said to add 15% for the 30" barrel? It is in very fine condition. I'd say at least 80%; if it weren't for the two flaws on the butt stock. The last 2 pictures show the small chip, and the small hairline crack. How much do you think these flaws drop it's percentage condition? I just took it to a local gun store/club; for the heck of it, and they gave me a range between 3500-4000. Seems low, but maybe not? Need to take a road trip for an expert opinion from Jaqua's. Any thoughts are very much appreciated. Thank you again.
