Alvarez mod. 5060 by Kazuo Yairi
I have a Alvarez model 5060, by kazuo Yairi, serial number 4140, it
is stamped 13-9-73, guessing it is the 13th day of september 1973.
but it conflicts with one persons Alvarez that the serial number is in the 4700's, they say their's is a 1972. can anyone verify the year of mine?
