The machine was blocked on arrival.

A quick surge showed a loose spring. Bring that in place, the machine was in perfect working and optical condition again. The machine demounted from the bottom plate. On the bottom plate was foam glued completely gone. Removed it with washing petrol. Cleared the machine and case an performed calculation test. It was OK and showed the good results.
This machine is very seldom seen. The A57 is considered as non existing any more. So again a very a seldom machine in clean and working condition again..
