Can you tell me anything about this?
I'm based on Dublin, Ireland.
A lot if these time recorders were modified in this way. Because of
the extreme high quality if the movement, these are quite desirable.
However, the fact that it is not complete, does detract from the
value. Still, they are very nice wall clocks. It looks like yours has
a beveled top which are more ornate and desirable than the specimens
with the flat top. We say take it out if the attic, clean it up, and
out it on display!
