El Jefe meant for you to look for the key signature on the bass strap. I think that the older Hohner 114 boxes had a T on the reeds. The T standing for the German city in which they were made. Now I know I am spellling it wrong but anyway here is my spelling.
Throssingen, Germany.

Yep, that's it ---the bass strap has "C" on it and the reeds are "T". It's tuned pretty wet, but I'd probably leave it and just back off the stop a little which takes some of the wetness out.
