Vintage Linhof 6x9 Technika type III / IV flat style silver lens boards to adapt and fit on 4x5 Technika cameras. There were two types, this is the first version for III/IV baby technika boards, it does not fit the later V 6x9 lens boards.

This will allow you to mount 6x9 lenses on Technika IV / V and Master Technika cameras built before the front standard frame slightly changed in dimensions (all cameras built before the early 1990s).

Good condition, working properly.
