I'm not a clock collector but I think the clocks
that had the 31 days marked on them were school clocks.

Railway clocks often had markings on them for 24
hour time keeping but I never seen dates marked.

Can anyone tell me if the early 1900 CPR station
clocks had the 31 days of the month around the
outside of their face. I saw such a clock in an
antique store and the owner thought is was a station clock.
