I did not repair this clock, just oiled the bearings and regulated it. It has the model name “Sparta” and a date code on the bottom.

The date code is 1901

This movement with the escapement at the back was used until about 1901 in Adamantine mantel clocks. It was superceded by the no. 89 movement. Note: the brass j-shaped turnback lever is not in the correct position because the previous repairer assembled it incorrectly. The long part should be on the left (time train side) and should have free movement toward the time train. See this post for how it should be.
