How about the "chopper" frame?
Seriously, not sure how rare they were to get back then, but white pad sets show up next to never nowadays.
I dont think Moeller has one. They were sort of the first 25 Mad Dogs, but they made a few changes and renamed them.
That photo is the ONLY photo of one Ive ever seen
How about a photo of K-9 D-ZINE
stickers on a Robinson frame , then? Rare in it's own respect
