I picked up a Super Dynaction for pretty cheap but I have a concern over it's authenticity.
The "Super Dynaction" engraving is definately home done. Now, the rest of the horn seems picture perfect. Excellent engraving on the bell, gold plated springs, BC bell-to-body brace, etc. Serial number is in the 11, xxx range (mid 1960s). The laquer is original. Is it possible it simply didn't ship with the "Super Dynaction" engraving and someone put it on later?
