Do you have any "before" pictures? I have a project I'm working on now that's nearing completion. I didn't think of taking any before pictures. I should have.
I forgot to take before pictures as well. I can tell you that it was a much lighter finish and the previous owner had sloppily varnished all the wood with over runs all over the receiver, trigger guard, etc. The upside is that the varnish had protected everything quite well.
Make sure to post some pictures of your project. Always enjoy seeing projects done by others,
