I know a guy prepping his parents house for an estate sale and he has an old acoustic archtop guitar. I told him I'd take a look at it (to see if it was something special) and turns out it is a no-brand model, but has (to me) all the hallmarks of a 1940's era box. There are no markings I can find, either on the outside or inside, though I didn't have a mirror to check under the top. I've linked a few pictures below. The guitar is in great shape, though it has a pretty good bow in the neck (nothing that would affect acoustic/chord playing, but you wouldn't want it for solos). Binding is intact and not overly cracked, and all the parts look to be original. I forgot to get a picture of the butt end of the guitar, but the trapeze tail is the two-prong style, not coming together in one piece. Apart from identifying it, he wants to know what it's worth. I said that even as a no-name, the original parts (especially the bridge and bakelite pickguard) would bring good money on eBay, and that a "sum of the parts" to me says the guitar is worth at least $200. I'd like to make sure it's not something more significant, or else he should be asking for more than that. If it may be worth more, I'd point him to www.archtop.com to request an appraisal, but that will cost him $35. I know it's a longshot, since this forum is mostly about electrics, but appreciate any insight you all can give me. Thanks in advance!
