Hey, like others on the list, I made my living as a bike mechanic back in the day. I like to tell my students that my first full-time job with benefits was as a service manager in a bike shop (and they shake their collective heads and mutter, "There he goes again.").
Thanks for the kind words about the collection. Definitely a labor of love. As far as value of the oldest, that would be my 1937 Raleigh Sports, which I bought for $32 (an eBay, local-pickup-only buy). It's worth a lot less than what Pastor Bob will often find at the dump.
