I've seen a couple Jeffreys dulcimers without labels, and one (from 1961) where he signed the instrument in pencil on the inside back panel. It's possible that the adhesive on the label in your instrument simply failed and it fell out, but you might take a good look inside with a flashlight.
If it is shaped like a Jeffreys, I doubt it is a copy. I have wondered, though, whether Jeffreys may have also sold kits, like many makers did -- I know he advertised in craft magazines, but I've never seen one of the ads and don't know whether kits were an option.
Not long after my initial post to this thread my computer died, rendering a lot of data unavailable (it was backed up, but the encryption key doesn't work). Unfortunately the address and telephone of Jeffrey's son in Virginia is in that data.It seems to be irretrievable, but the man's name is Jeffreys and I remember he is still living near Staunton. Your post inspires me to track him down.
By the way, Ben Seymour is doing a complete re-fret of a Jeffreys for me. Imagine those sweet plaintive tones of the Jeffreys intoning in equal temperament! Yum.

I believe that I may have an early model of an A W Jeffreys, Jr. dulcimer. When I purchased it in Houlton, Maine a number of years ago, it came with the booklet that has been mentioned earlier. It is the revised version (1964) that I have. However, the dulcimer is not signed, so it is possible that someone could have made a copy of one of Jeffrey's dulcimers. The description is similar. The action was high, but I had it lowered.
Anyway, I wanted to comment on this thread...after all, it was a search for information on Jeffreys that has led me to this site and I think it is going to be a good place to hang out.
