Joost — The sandblasted (not etched) weights & measures mark shows that it has been checked by the authorities and can be used for retail and other legal purposes.
Translation:-
GR — George V and VI.G2R — George V and VI, the 2 possibly a mark of the City of London.24 GRADS — 24 graduations tested (this stops more being added).14 GRD — 14 graduations tested.545 — Weights & Measures Office number for their York office (not the whole of Yorkshire as there were several offices in the three ridings). Unfortunately this does not help with identifying a manufacturing glassworks.Dagger in a Cross in a Shield — I've not seen this before. The dagger represents London's Guildhall, which, with the cross of St George, becomes the arms of the City of London. So the City of London (i.e. the square mile) Weights & Measures Office. Again this does not help with identifying a manufacturing glassworks.
The same type of mark was used on all measures. In December I saw a similar mark on the massive Avery weighbridge at Quainton Station, used for weighing railway trucks full of commodities like coal.
Joost, that City of London measure is a real gem. :hiclp: :hiclp:
