[Trombone-l] 5B question

[Christopher Sayles]

I have received a question on the 5B that I cannot answer.

First - was the 5B actually made in the 1950's or could this horn that I 
listed be a King 1410?  The question by the buyer was if it was a 
model1480.  I don't think the specs work for a 1480, but could for the 
1410.  Did King even make the 1410 into the 50's?

The horn does not actually have a model number stamped anywhere on the 
instrument.  I had played a 5B in the 70's that had 5-B on the bell.
