I always try to photograph these old cast-iron mile-markers whenever I spot them. This one was on the road back from Helensburgh today. Cont./ #glasgow #milemarker #castiron #helensburgh #dumbarton

How old are these signs? They obviously were not designed with motor vehicles in mind due to there small text and height off the ground...

I'm not sure, but I'd guess it was but up sometime between 1850 and 1900.
