Your Spiralator is mint and lightly used. Older ones are usually missing a lot of enamel. I'll show you a pic of a well-worn one tomorrow. The tub is beautiful, too, and for twenty bucks--what a steal!!! Nice.
I Have a knob for that lid; it's the same as the spindrier lid for that period, the washtubs obviously being identical for wringers and spinners. Email me your address and I'd be happy to send you the knob.
As for the amusing wood, I was surprised as you were to discover wooden blocks inside a wringer. These brands all used wood: Kenmore, Norge, Blackstone, Easy Mc Clary (yeah, I've got a square, full-skirted Canadian wringer), Wards, and maybe more; these are the ones I've opened up. But hey, windmills and wooden shoes last a long time, too!
As for that weep hole, I'm stymied too; never seen that before!
Thanks for the pix. Love that unique lower control center--so cool. I'm envious. What a beautiful machine. The feeding tray is a breeze to paint.
More on the coupler and Eugene's part tomorrow.
