For sell is an Alpa ground glass (https://www.alpa.ch/en/article/ground-glass-set-pgs-complete). The unit is 99% new, and is rarely used. Ground glass comes also with original Alpa box/packaging etc.

Come with the ground glass is an Alpa Leather Focusing Bellow (https://www.alpa.ch/en/article/leather-bellows).

All these Alpa equipment are genuine, not aftermarket substitute.

I am leaving Alpa because the company is not very supportive to film applications now.
