Gustav Becker 2-weight Vienna Regulator, 1875-1880.  A 50-inch Vienna in good condition but with a replaced crest.  The case is rather simple and the crest is not quite a match, and may be hand-made.  The door glass is modern, the two-part porcelain dial is good, the hands are period.  The two weights are very tarnished, the bob is shiny. The 8-day time-and-strike movement is running and striking.  $200-$300.
