Not-a-clue on age, but it's in the size and style I lean toward. Coupla quick observations and a question:
It's pretty clear that the base was heated and the plug shoved in to expand the horn a bit tighter fit. Nice.
The nails look pretty modern, but I'm no nail expert.
The plug is surprisingly "blond" or unsoiled, making me wonder if it was use much, or if it's a more recent build.
Now my question:
I like the low profile of the strap hanger on the plug. Do you have a better pic of it?
Thanks!
