So someone was throwing away two reasonably-intact Beseler 45's...one is an MXII and the other is an MXT. Neither is in great shape, but I can salvage and swap enough parts off of one or the other to get myself one really nice working unit. The only issue that I've found that's going to be a bit of a pain is the fact that at some point in time a previous owner (or moronic college student...as these originally came from a college darkroom) has removed the counterbalance spring retaining screw in the lower cross tube. Is there a simple way to access the interior of that lower tube and put the spring back in place? I know how to set the tension on the spring once it's in - at least, according to the manual - but there's nothing about actually re-seating the spring itself. How the screw got removed, I'll never know...it's the ONE piece that the manual says to never touch. Just my luck that someone monkeyed with it. Any help is much appreciated. Note: I can probably swap the other carriage/cross tubes into place into the frame that I'm using, but the nicer of the carriages is the one that has the missing screw. That's a last resort, and since the enlargers are being taken completely apart I'm not averse to digging inside of one.
