A saturated solution of alum will dissolve the steel screw over several days (it won't affect the brass). I let the piece sit in a plastic or glass container in the oven, which has a pilot light that keeps it around 100F when not in use - optional, but I think the warmth helps speed up...
A member on here, TorsionKid, has both the gimbaled top block and pendulum adjustment rod for sale on eBay. Search for "pendulum adjusting rod" and "Hauck gimbal suspension". His reproductions are identical to the originals.
The pink alabaster base is unusual to me; I usually see those on Kundos made for George Borgfeldt's 'Coronation' line, albeit with a slightly different design. All of the Mayer Kundos I've seen have a brass base. Either way, they are beautiful clocks, and were made in the early 1930's, when...

Expending a lot of elbow grease, if you don't want to keep it heavily tarnished. To do a thorough job, it would be necessary to dismantle the case into its various components, not a job for the faint of heart! It will be a beautiful clock when finished; this case and pendulum are somewhat...
Plate 1419 is for a clock made by Phillip Hauck, and the pendulum you describe should look like #6 on Page 195, which is also by Hauck. The bottom block should be a snug fit into the hook on the pendulum, and anything that fits will work. We would love to see photos of the clock as well as the...
It sounds like the shipping gods took pity on this clock and didn't do any serious damage! I have a similar Hauck Louvre: Post Your Ph. Hauck 400 Day Clocks Here, serial #25294. also with the "chronometer" pendulum.. It is a pleasure to live with!
A truly beautiful restoration. I have owned a bronze four-glass Tiffany double-contact case for years, but have never found a movement for it - seeing your case has made me wish once again that I could!
