Did some acquisitons of late in the category of bellows lenses.
A Schneider-Kreuznach Xenar 135mm 1:4.5 in M39 mount. Its serial number indicates that it was produced around 1960.
A Novoflex 105mm 1:4 in Minolta MC mount, with automatic diaphragm and meter coupling. It has a front ring added to the lens which I couldn’t remove despite some fairly forceful attempts.
