May I be permitted to do a little crowd sourcing (now an Olympic Sport for organizers after the empty seats fiasco)?
The other day we purchased a job lot of knobs and knockers (no, please...) many of which were manufactured by Archibald Kenrick & Sons of Union Street Birmingham. This magnificent firm is (atypically) still going strong having started life as an iron founder in 1791, a reminder of our wonderful history of "making things" in the days before "workshops" used flip-charts and insurance policies became "products".
One of the items in the box is a hinged casting with the maker's name, "No 8" (possibly) and the numbers 4 1/4 x 3 3/8 which is the backplate size in inches. It looks like some sort of bell push but the lever side is obviously the exposed side as it has been painted.
Any ideas of a sensible or non-sensible nature would be appreciated.....
