SOLD - The Doublemint Petzvals

SOLD OVER ON LFPF

Double your pleasure, double your fun!!!! If you have no idea what I'm babbling about, here's an old Doublemint ad from the 80's: Doublemint Twins

What we have here is an outer brass barrel that takes either of the 2 included petzval lenses. One lens is 6", the other is 10", so you have choices. Obviously they are both the same diameter glass, so the 6" is a blazing f2.7 and the 10" is a little faster than f4.0. I actually measure the 10" as 9", but it is marked 10, so I sort of have to say it is 10"...

The brass 'lids' can be removed. The glass looks good. There is a little separation around one of the front lenses (forget which one) but I couldn't see it until it was removed from its mount, so it is minor. No flange. About 3" diameter at the threads. Focus knob works fine.

Now, I know they look pretty nice. BUT, there are problems...

The 6" barrel has a small dent in it (circled in second photo). Both front lenses are loose in their mounts even when they are properly screwed down. This doesn't affect anything but it is annoying to hear. A small piece of felt behind them would probably fix it. The rear elements are nearly impossible to remove and put back together. I did it, but it took a loooonnnggggg time and I'd never do it again unless I had to.

As nice as these might look, these no-name lenses are not Ross and Dallmeyers. The machining is shoddy, things are difficult to get threaded and screwed in, metal is thinner than it probably should be. These are users and not collectors. BUT they throw a nice image on the ground glass, and you are getting 2 for the price of one, so it isn't all bad.

Price: SOLD, I'll pay the insurance. Paypal and USPS money orders are ok. PM or Email only please. $$ to APUG if sold here.
