Edward Korfhage and Son tower clock from Buer, Germany, c. 1950's.
Three train with hour and
quarter hour count wheel strike. Combined cast iron flat bed with plate and spacer
construction. Graham deadbeat escapement with adjustable pallets. Planet and ring gear
maintaining power on all three trains. Movement is equipped with a 60 second, differential
type, gravity driven train remontoire. Movement is designed to be both electrically and
manually wound. 38"w x 55"h x 30"d.
This is to date the most complex
tower clock I have restored. There are 579 individual parts. The condition as found was in
fair condition as far as oxidation. Basically a B- on an A-E scale. This
is, next to the completeness of the movement, the most important factor determining the
difficulty of a given restoration. Total time to complete the project 276 hours; finished
in May 2006.
All parts were stripped down to the
bare metal; all traces of rust removed. Every square inch of the clocks' surface is
covered by a protective coating (pivots and pivot holes excepted). All bolt heads and
bushing faces were machined to obtain a damascene finish. This change, plus the fact that
the overall finish is superior to that from the factory, are the only departures from the
original specifications of the clock. I generally keep to the original specs, but do stray
when I think that the movement's look will benefit from the change. They are usually
minor. Below are some before and after comparison shots. The color is a close match,
however, a flash was used on the before shots resulting in a color shift.
