I picked up an old Beseler 45 MCRX yesterday. It didn't look the best, but with the help of my five year old daughter, I got it put together, and cleaned up nicely. Now I have a couple questions.

1. Can the gears and bars that the head slides left & right on be greased? If so any recommendations on what to use? The gears especially are very stiff.

2. How do I tell exactly what kind of colour head it has? Basically it's a lightbulb with a single lens.

3. Should there be some sort of tray in the filter drawer?

4. Now for a really basic question, is there some sort of standard for lensboards for enlargers? I'm curious as the lensboard from the B&J Solar I have fits on the Beseler.

Thanks,
Zane
