I found this guy on CL selling a 1967 Dual Showman in San Antonio TX.
He only wants $450 for it which sounds like a steal - not sure if this is a Blackface or Silverfce model - I didn't get into any of that with him - but it was still avail this morning. He says it works well incl the Tremolo.
His name is Adam Gutierrez and his email is
withchildd@yahoo.com
Good Luck all!
