Most interesting stepped lock examples by T(Tadeusz?) Wisniowiecki we Lwowie:
Lock with WISNIO WIECKI engraved from:

He may be missing a decimal point in his price, but I don't think any contemporary mechanic could have produced anything with more quality.
Tadeusz Wisniowiecki may have been born circa 1818.
Piotr J. Bochynski has located info on Tadeusza Wisniowiecki of Lemberg/Lwow and he died circa(11.26.1881?)1881/1882 and might just be at No. 8 plot in the Cemetery(Cmentarzu) Lyczakowskim. A.W. Molnar was his successor.
