This is the portrait lens for all of the Mamiya TLR models. The glass is clean with no haze or fungus and the shutter is strong and accurate (this model usually has haze in the glass.) There is an engraving on the rear (see photos) but it is only cosmetic and it is not visible while in use.
This is the later version and works on all of the TLR models (including the C33 and C330). It comes in the case with the original caps.
The shutter is strong and accurate. The glass is clean and scratch-free. The body shows very light wear.
