It could have been made from components acquired from the Sauer shop, or some other, in Suhl just after WWII but I do not see any marks that lead me to believe it originated @ the Sauer facility. Did Hendrik Frühauf say it was engraved by Heinz Funk, or what is the source of info there? I wonder if it was by Franz Schilling?
It does have the screws for the upper & lower scears.
I'd be hard pressed to attached anything Sauer related to this example.
Any idea on the text on the water-table? Is it German, English or Arabic?
Cheers,
Raimey
