Here's a lovely 2-weight Vienna Regulator, c.1890 by the much sought after European clockmaking firm of Gustav Becker. There are a lot of photos below to guide you through the evaluation process.
Physical: The walnut-veneered fruitwood case measures 17.75"w x 45"h x 8.125"d and is in excellent, age-appropriate condition with original finish, finials and crown. The 6.375" diameter dial is original to the case. There appears to be a touchup to the numerals in the XII-II area. The weights show that they've been around. That would not bother us, but the good news is that weight shells are readily available inexpensively at timesavers.com.
Mechanical: The eight-day, time-and-rod-strike movement, s/n 850579, is in excellent running condition. Please note that this clock strikes on a rod, which is significantly more pleasant to listen to than many clocks of this genre that strike on a tinny-sounding coiled gong... BIG plus about this clock.
Comments: Lotta clock for the money.
