My "featured" LTM lens of the the week is the W-Nikkor-C 3.5cm f/3.5 Nippon Kogaku Tokyo.
This is an older version of the M39 mount that does not have 34.5mm filter threads. Fortunately the Leica SOOGZ filter adapter fits this perfectly and will allow use of 39mm filters which are needed for black and white (shown installed in the second image below). FYI - the SOOGZ adapter also fits the Nikkor 2.8cm f/3.5, 3.5cm f/2.5 and 5cm f/3.5 lenses.
Samy - it will probably fit your collapsable lens. If you want to send it to me I will test it
Third image is a shot using this lens with Orange filter.
