At least it is the only of its kind I have run across. Perhaps for a
good reason.

My last visit to the NAWCC museum had this one in their workshop display.

I had considered mounting something like this, without all the chisel
and miscellaneous tool racks, in the narrow space between the windows
over my bench but in the past year or so my saw collection has doubled.
(Up to about six, don't laugh.)  At this rate I will probably outgrow
the till before I find the time to build the thing. Yes Eric I'm listening.

Plan B and probably the most sensible idea is to decide which clock
movement I want to dedicate as shop clock and hang it in the space instead.
