Glad to hear about your motorhome, but sorry to hear about your friend. It pains me to think that all of us pinheads will end up having to sell off our collections at some point, for the inevitable health or age reasons. Or to help pay for a kid's college. But I'm not going to worry about that for now! I did send a request via your website.
Just out of curiosity, what four pins did you keep? I'd have a tough time narrowing down to just four pins.
