1923 Kienzle Regulator Wall Clock

I am willing to negotiate the price down further based on wear and tear due to age, service costs and minor repairs, feel free to make an offer and I will take it into consideration.

I am willing to provide the patent and production serial numbers to you if you wish to do your own background checks on the age of the clock, I removed them from the pictures provided.

Apparently, these clocks built with Westminster chimes are rare. The pendulum stick is broken so I taped it to test the mechanism but it can be restored with resin.

INFORMATION:

The Trademark Logo is Kienzle GmbH / Kienzle-Haller AG / Schlenker & Kienzle issued in 01.06.1923.

There are 3 patents ingrained on the clock's mechanism.

The first Deutsches Reichspatent (DRP) refers to an innovative movement design that allows spring barrels to be removed without dismantling the entire mechanism was issued April 9, 1915 with the protection back-dated to June 1912.

The second Deutsches Reichspatent (DRP) refers to a technical improvement in the clock's striking mechanism was issued in January 30, 1922 or 1923 with the protection back-dated to April 8, 1921.

The third patent is a DRGM (Deutsches Reichs Gebrauchs Musterschutz) which specifically relates to a device used to regulate the beat on pendulum clocks. This patent was enrolled to Kienzle Uhrenfabriken as of April 30, 1921.

Renewals of these patents and utility protections were expensive back then so unlikely for the company to renew it according to the information I found hence way I think the clock is no older than 1923.

I can't find any records of patents being renewed based on Deutsches Reichs-Gebrauchs Muster (DRGM) archives which was the patent company back then.

Exact pinpointed information is limited due Kienzle's workshops, offices, and sales headquarters were destroyed when the Allied Forces did bombing raids during World War II.

This is the original Kienzle Dial, Solid Oak Box, Brass Pendulum and Key based on the manufacturer's designs.

I am no expert but I feel confident in my findings, unless you can prove otherwise.

CONDITION IT IS IN:

The Solid Oak box itself is fully intact and has all the supports needed to wall mount it.

Couple of small drops of paint on the top of the box, out of sight.

The wood which connects to the pendulum snapped into two.

Both dial hands still rotate whilst ticking.

All chime "hammers" still work to play a tune.

All 3 key winding holes still turn to wind the clock.

The glass is still intact without any cracks or damage.

Some marks, scratches, discoloration on the inside of the box.

Some tarnish.

Dial has some finish missing.

It has to be sent for a service. I am unsure if sometimes the chime arms do not stop chiming which can be held in place to solve this problem with the rope stoppers, it could be a problem with me taping the pendulum and it being the incorrect length which the correct length is 40-49cm set to 104 BPM.
