lensboard hole size for a Componon-S 5.6 135mm

[JeffD]

Hello,

I recently was given an enlarger (Beseler 45mcrx) and have a schneider-kreuznach Componon-S 5.6 135mm I would like
to use with it. The lens diameter is to wide to fit in the lens boards that came with the enlarger.

Can anyone tell me what size hole I should be looking for when looking for a lensboard to mount this in? Any ideas where I could get such a lensboard?

Thanks!

You're holding the lens. Best to measure it.

Looks like 50mm but best to measure your lens.

50mm is a stock part and you should be able to order it new still. If it's not 50mm then you could get a blank board drilled. If you don't want to buy new then Ebay?

The LF forum lists many.

Mine is @ 39mm, unthreaded, I use a jam nut. I have a 23CII 4"x4" lens board.

Try measuring it? I am sure B&H has exactly what you are looking for.

Thought it was for lensboards on LF cameras...disregard my previous post.
