Hi everyone. This may have been discussed elsewhere, but I couldn't find what I was looking for. In any case, I just recently bought a Dallmeyer 3b, and there were a few things I'd just like to get advice about from you more knowledgeable photographers. The 3B I bought has a serial #68207 and has a barrel sleeve with rack and pinion. It appears to have a thread for a hood with a small lip (almost like a mini hood), but no hood was included. I guess my first question is how come I always see 3B's that are simply a straight barrel with the aperture adjustment lever only and a turn to focus engraving? Mine seems like a slightly different design and has aperture markings that stop at f3.5 rather than f3.
Also, the front element couplet is showing a bit of edge separation, as well as a 3-4mm spot towards the edge of the glass that appears to be a separation. I figure this lens is just fine to shoot with, but since I've been pursuing this lens for quite some time, I am hoping that maybe I could get the elements separated, cleaned, and recemented. However, I am nervous about having this attempted as I know there might be a possible risk of cracking, etc. due to the heat used in softening the original cement. I just don't know if it'd be worth the risk, but maybe you guys can appease my concerns. I've emailed John over at FocalPoint to see what he thought, but some of you might have suggestions or experience in recementing one of these older lenses. Sorry, no photos of the separation yet as I just picked this up from the post today.
Any help or advice is much appreciated!
Thanks very much,
Jordan
