Thanks for your help guys.

I found one a couple of weeks ago SN 41507
And still working…lol

https://www.building-center.org/ is a good resource to keep on hand.

But it looks like you’ll have to call Clare to get the exact date…look it up at above link, if you want.

Thanks, I love discovering old operating stuff, it brightens my day.

Good but old for sure.


Found a real oldy still working.

Then the age verification is a moot point, n’est pas?

Edit: Oh, I see it’s an old thread…
