Seiko 'B' shutter - 48MT

[Ig Nacio]

Hi,

I was reading this other thread about Seiko shutters, here:
https://www.largeformatphotography.info/forum/showthread.php?167650-Seiko-Shutters-Reliability

and I started wondering about this one particular shutter:
the Seiko 'B' shutter 48MT, or 48 mount.

Can you tell me a bit about this shutter? What lenses go
with this shutter? Their lens boards are very uncommon
compared with the Copal 0, 1, and 3 shutter lens boards.

Thank you, kind regards!

Hi,

I don't seem to find much information about lensboards with '48 mount' or '48MT'
for the 'Seiko B' shutter.

Could you guys please share a bit of information?

Thank you, kind regards!
