I have a Nikkor-W 300mm lens in Copal 3 shutter for sale.
I had it on my 8x10, and never had a single problem with it. Works great, looks great. I have no way to test the shutter speeds, but they seem right on as far as I can tell. I haven't put it under a microscope or anything, but the glass looks nice. Maybe a tiny bit of dust. Has front cap. No back cap.
I'm getting into wet plate collodion and I need to free up some money, so I'm selling a few things. In fact, I may be putting up a 12x20 camera and G-Claron 355mm lens soon. If interested in those, let me know.
I can send pics of the lens if you'd like, but it looks great.
I saw one of these go on ebay recently. It went for $699. I'll take $575 for it, plus shipping. Seems reasonable, I think.
Thanks,
Steve
ps: You can look under sdivot on ebay and see that I have perfect feedback. I've been a member here for a while. There might be a person or two here who can vouch for me. Maybe Jim Galli would. I've bought a few things from him (who hasn't? lol).
If you buy anything from me and you're not happy, just return it in same condition, and I'll refund you're money.
