13.5cm f/6.8 Hekla Doppel Anastigmat

The shutter needs to be serviced as the speeds are inconsistent/variable. Lens is without haze/separation. Some cleaning marks present, but otherwise very clear. 

Bellows are in good shape and appear to be light tight. Camera adjustments are smooth. Leather is in overall good condition.
