All W&A drums in the Perfection era were hand signed & dated, in pencil by Robert G. Benoit. He passed away in the early 80's i believe ( i:m not positive when ). I think it's amazing that one man hand built each drum & signed it before leaving the Worcester or Auburn plant.
I have W&A's with '69, '71, & '73 dates. I am planning on picking up a set of '72's this weekend.
