I expect that you are referring to the Casuals College that he put on way back. I used quite a few tips from him. My late father+in+law's second wife had a very nice formal portrait taken by him in Oklahoma,

I was reminiscing about some of the past photographers that I have known or met and came across your post. Nostalgia is still with us.

Craigslist is another good place to sell since it is more local and the buyer can pick up. I too have darkroom equipment that I should sell.
