Glad to announce the one at the top of this thread was bought by a gentleman in Wyoming, who just joined our Chalet owners' forum. He's really enthused about continuing its restoration.
Meanwhile, here's a
link for a San Fransisco Bay area one - the seller says it's serial #1560 built 11/76. Call his direct number 707-874 3535.
And as ever, I do these favors for the sellers for nothing more than the #s & build dates of the rigs....
