This isn't a sales pitch, but more of a question which will hopefully help me out when I go get ready to sell some things on eBay. I have about 15-20 lenses out of Altman 65Q Fresnels. The ones I have are the older type ( somewhat wider spaced rings and bigger bullseye) but are free of chips and cracks. What do you think the value would be per lens? I was thinking around $10. I also have about 8 x 5 5/8 roundels. Some plain and some spread, various colors. In perfect condition, what do you think those would sell for? Lastly, I have a TON (well, a pile of about 40-50) of c-clamps. Mostly Altman, but also a few Grand (not dnarG), one mega-clamp, some of the Altman "Heavy Duty" clamps, a few that look Altman but have no name, and also one really cool "Little" clamp. It is about the size and look of an Altman Heavy Duty but is aluminum and has a declared SWL of around 250# or so. What would you charge per clamp, or per lot of 4 or so? ...Afterthought... Is there a market for 65Q shells, yokes and colorframe holders, or should I just look at scrapping them out? I have like 13 or so. They would need to be repainted and of course furnished with the lamp/reflector assembly and lens (OR your favorite lamp shade) to be usable. Again, I'm not trying to sell these right now, but I am going to be listing them on ebay within the next few weeks. Right now I'm just trying to get an idea of what it's all worth.
