So which you got? You have no idea.

Then Wurlitzer waas made by a few makers.

Was it Martin

Was it Buescher

Was it Holton

Was it Conn

So which you got? You have no idea

Then the older models often had bad keywork and soldered on tone holes.

The newer versions had a front F.

So what you got? No Idea.

That is the reality. Its like asking what an old car is worth and giving no specifics.

Here is my overal answer. Your Wurlitzer is probably made by Martin. It would have nice beveled tone holes that extend in a curved fashion to the pad seal area opposed to being just straight. It probably is an older model based on the serial number. It is probably a C melody, which is no longer used much, or a tenor in bflat as you mentioned. Probably silver plated with a gold wash in the bell.

It is worth a few hundred dollars at most As Is. It will cost 600 or more to get it playing. Then it would be worth maybe 575 bucks. Also, we have not covered its actual condition.

Pictures would help you get a more definite answer.

Good Luck.
