Another request for help ID'ing Bass

[John Wheat]

Thank you for any help in advance.

I recently purchased this instrument on a prospective guitar buying wild goose chase. I know next to nothing about unfretted string identification or value and hope to become better informed by the obvious expertise inherent to this forum.

What I think I know:

-Recently purchased from a couple in their late eighties in central Indiana. It had belonged to a long deceased brother; the couple know nothing about the bass.
-Was repaired by T.G. White in 1969. The only other marking inside the instrument is a sticker from the Fuller Violin Shop, Fort Wayne Indiana, possibly where Mr. White worked. Both Mr. White and Fuller Violins are apparently long gone...
-Carved, most likely German or Bohemian late 19th/early 20th century.
-Plays and sounds very good in my limited opinion.

Dimensions:
String length: 41.75
Top length: 43
Back length: 42
Upper bout: 21
Lower bout: 25
Rib: 7.75
At neck: 6.125

Again, sincere thanks,
John Wheat, M.D.
