M25 but 0.75 or 0.5 pitch? Schneider-Kreuznach Componon 50mm f/4 enlarging lens

[Chan Tran]

I have this lens and want an adapter to mount on the Nikon F bellows (Nikon PB-6). I know it's 25mm but what's pitch. I see adapter from M25 to Nikon F but 0.75mm pitch and the M25 to M39 adapter has 0.5mm pitch. I suspect that it is 0.5mm but want to make sure.
Thanks,

They made 25mm to 39mm adapter plates for these enlarging lenses.

All of the M25 thread enlarging lenses shown on this website are M25x0.5 (including Schneider-Kreuznach):

That's what I thought. So I have to use a M25 to M39 adapter along with the M39 to Nikon F adapter. They make M25 to Nikon F adapter but only in 0.75 pitch.

You might look at this website for a machinist in Portugal. He has several stock adapters, and I believe will do custom work, too. I bought an adapter from him a few years ago -- it took a while to get it, but it was very nicely made:
