Who is Martin Baris? You got me there
Thom has written about a Martin Barry.
The only other markings I've seen to have caused confusion (regarding sopranos) have to do with the "Made in USA" stamp. Apparently, at some point (after they stopped using the rear headstock stamp we are familiar with), Martin made ukuleles for export. They stamped USA on the back of the headstock. On several occasions, sellers have claimed that their post-62 sopranos with the "Made in USA" stamp inside the sound hole were earlier models made for export. A little bit of information ...
Obviously, dating Martins can involve some investigation and uncertainty. The point here is I called Gryphon about that specific ukulele some time ago. Whoever I spoke with told me the back had been replaced. Why else would the price be as low as it is, as compared to the other one they have? I purchased a 1K from Gryphon a few years ago. They described the ukulele in detail to me over the phone. If anything, when I received it, it seemed that they had been very conservative in their conversation with me. That is, the ukulele looked better than I thought it would. I can't understand why Steve was told what he was. Must have been a newbie on the phone.
