I really need to stop buying old, interesting cameras.
For various reasons, I decided to purchase a RB Series B 3x4. It's in.... "fair" condition. Which means it needs some work before it'll start taking pictures.
So it's a 1932 (? SN # 178620) Graflex RB Series B 3.25x4.25, with the black 6 3/8 No. 32 lens, and a Suydam 120 film holder. Yes, I'm aware of the joys of a 3x4 Graflex back.
The camera was neglected, but not abused-- it's dirty, the lens was like looking through a fog bank, the focusing rack is stiff, the ground glass was a hazy shade of brown, the tension knob didn't like me, and the shutter curtain... well, apparently it hadn't been unrolled in the past 30 years. The leather is, by and large, complete and in good condition. There are a couple small tears that might need repairing, and the piece over the lens door is coming loose (it's pulled out from one of the rivets).
The lens cleaned up nicely, I got most of the gunk off the ground glass, and by carefully rocking it back and forth, and applying firm, but gentle pressure, I loosened up the curtain one slit at a time. It seems fully intact, although it's got some creases from where the apertures were rolled against the fabric-- but it does seem to work freely now, in all positions.
The tension setting was more persnickety-- whatever passed for lubrication has passed on, and is now more sediment than lubricant. It works, it releases, and it seems to increase tension, but it is stinkingly stiff, even with the curtain set to O.
Mirror operates smoothly, and isn't too nasty. I'll try cleaning it with a low-pressure blower I use for such things.
The questions...
1) Is the mirror front-silvered? How tricky is it to clean?
2) The ground glass appears to be held in by two clamps, each with 4 screws. If I just remove the screws from one bracket, can I remove the ground glass? Do I have to worry about getting it back in the exact right place, or will the screw holes serve as my guide?
3) The bellows is shot. I could make it light-tight, but it's in bad shape-- most corners are deteriorated and many edges are failing. Making it light tight would essentially be rebuilding the outside out of bookbinder's tape. Is there someone who makes bellows for the graflex specifically?
4) I've seen videos on dismantling the shutter mechanisms-- I don't want to pull the shutter if I don't have to, but I think I need to pull the tension mechanism at least, and clean / lube. Any tips?
5) Finally, the only thing that Does Not Work is the shutter release-- It trips the mirror with no problem, but nothing happens to the shutter. --- Never mind. "T" setting. *sigh*
I'll probably have other questions, but surely, that's enough irritation for now.
Thanks!
