Schmid - Schlenker was a German manufacturer of small mainly table clocks.
They made a large number of models between the years 1950-1980. Many were smaller-scale replicas of old French models and others were clocks created by them.
They are not highly valued and they are not of very good quality either, they used a lot of low quality plastic and brass.
I've worked on a number of them- wall, french and novelty styles. I'd consider them lower end- though one of my customers paid a pretty good dollar to get hers fixed like new. Only took a bushing in each hole... a long bath and rinse (hadn't had one in its' life) and a bit of rework on the escapement.
However, client was elated to see it going again, so it shows again, each individual has their own cherished possessions.
