Your clock looks identical to one that I have. The following describes my clock:

The works are brass using plate number 33485. Schlenker & Kienzle used the trademark as shown below in 1889 and again in 1897. The clock face is composed of two-pieces of porcelain mounted with brass dial rings. The pendulum has an “RA” on it’s porcelain face. The “R” stands for “Retarded” or the adjustment to make the clock go slower; the “A” means “Advance” or the adjustment to accelerate the timing. In between is an arrow which points to the adjustment screw on the pendulum.

Currently, the clock keeps nearly perfect time after being made in approximately 1890.

The clock chimes on both the hour and the half-hour. The trademark on the back plate looks very similar to the below trademark from reference (1.) which indicates that it is a Schlenker & Kienzle clock.

In addition, the swing arm (the arm that the pendulum attaches to) has the initials: D.G.M.S., which stands for the German words: “Deutscher Gebrauchs Muster Schutz” which is translated as German Sample Protected.

Johannes Schlenker was born in Germany in 1797 and is the patriarch of the Schlenker & Kienzle Clock company. He founded his first clock company in 1822 in the Black Forest of southwest Germany in Schwenningen, Germany. It was perhaps his son or nephew, Elias Schlenker who was born in Schwenningen in 1828 and was a famous maker of cuckoo clocks, also in Schwenningen.

Christian Schlenker apparently took over the Schlenker clock works from his father. During this period, the Kienzle Clock Factories was a competitor in Schwenningen. In 1883 Jacob Kienzle married Christian Schlenker’s daughter, Agathe Schlenker. In that same year, Christian Schlenker founded the Schlenker & Kienzle Clock Company with his son, Carl Johannes Schlenker and his son-in-law Jacob Kienzle as partners. Due to high impact duty to Austria, a branch factory was opened in Komotau, Bohemiz, in 1887. In 1922 the company was changed to a wholly family-owned stockholder corporation under name Kienzle Clock Factories, Inc. The clock was probably made in 1887 in Schwenningen, Germany. (1.)

Thanks Bob, I appreciate your response to my photo request for information on this clock.
The information was gratefully received by my local bishop in Sydney who owns the clock. I saw it on a visit and asked about it and took a photo to find out more than the scanty knowledge he had of it.
My father collects old clocks and I appreciate the history and good workmanship in any timepiece. It is humbling to remember that several clocks in my parents home have ticked and chimed through the duration of 4 generations of my family.
Psalm 90 calls: "Teach us to number our days, that we may gain a heart of wisdom", and Matthew 25:12 concerning the return of Jesus: “Therefore keep watch, because you do not know the day or the hour."
