HI Kev, to answer your question about dating the machine
the longer I looked at the pic, the more it seemed older than those in the Crystal Beach Laundromat. Then on seeing your later pic of the ones in the basement, the two in the back next to the boxes, those are identical to the ones I saw in 60-63. So now I'm sure your new find is older, 55, maybe even earlier.
And Happy Birthday, Big Buddy!
