Hmmmm. . .
I'm not a man to price things. If I were, I could afford a lot more things I've wanted to collect.
Rislone was available in the mid-60s, I know for sure. Whether it was available before then, I do not know. I KNEW that name is familiar. Would you believe, though, that I used an old bottle of Rislone loosen some rusty bolts on my 96C??? It's probably pretty rare, but I don't know how many people collect lubricant-related items. Hard to find, yes, but desire?? It does have a nice big graphic!
