Ah! That is more appropriate than you realise. There's some speculation online that the Trinol, like the 105mm "mountain Elmar", was originally designed for use on medium format but fitted to a mount for Leica. Two reasons: 1, there's strong mechanical vignetting at f/3.5, suggesting this mount is a bit of a cludge (see the attached test shot from my M240), and 2, the lens head and mount were made in two different places (the head in Leicester, the mount in Scotland)
