Based on your pictures and my little knowledge of guild/dearmond bluesbird and s10 models, i found a few red flags you might want to check:
-trus rod cover should have 2 screws like gibson (or 1 screw for dearmond mik)
-decal on headstock should be a tower-like logo
-horn shape should be rounder (for older models)
-no poker chip
-bridge should have small post like gibson
-most have block inlays
-back of the headstock usually has mia or mik
Just my 2 cents. Let's wait for the real experts to chime in.
