I still have a few too many petzvals so I thought I'd throw some up here for you to look at during time outs in the games...
Please PM or EMAIL if you want one or have a question. USA shipping is $9 for as many as you want to buy. I don't mind shipping overseas, but it can get fairly expensive. Paypal and USPS money orders are fine. $$ to APUG is sold here.
The glass is good on all of them. there may be a few cleaning wisps but nothing serious.
#1 - A MacIntosh Stereopticon (pre-Apple Mac, no doubt...) Approx 7 " focal length, approx f4.5, non-original shade hood. I had one that fit, so put it on there. No flange, approx 55mm diameter at threads, working focus mechanism; Price $122
#2 - William Brown & Earle, approx 6" focal length, approx f4, has a flange; diameter at flange approx 3"; working focus mechanism; price $133
#3 - No name 6" with sun shade, no flange, approx f4, diameter at threads approx 55mm; working focus mechanism; price $120
#4 - Erker Bros (a St Louis retailer still around, I believe) approx 13", approx f8, flange. Diameter at the threads approx 3". This one is not going to swirl, so if you are looking for that old smooth tone from a petzval without the aberrations, this will do easily for whole plate and possibly 8x10; working focus mechanism; price $145
#5 - B&L projection petzval, focal length is 4.5" and f3.2. These are cheap and can be a lot of fun, if you want to try for swirls on 4x5. If you get the internal restrictor ring out of it, you can get it to approx f2.5; price $65
Thanks,
Richard
