How to identify MLU version

[ssakari]

Hi,

I am looking to buy Pentax 6X7 with MLU. What is the most easy way to identify MLU version?

Its got a switch on the right hand side of the lens mount (from behind) exactly on the opposite side of the flash connections. Best to ask to seller..

Ask for a demo.

It has a small lever/switch adjoining the lens mount, visible in the top photo here:
