R3 - possibly, but that is a WW2 vintage extinguisher, and I'm looking for a couple more (or a similar new type) as part of a MV restoration, not for use.
The refurbished DT sized ones (not WW2 but relatively recent manufacture, maybe 10+ years old - CO2 units now seem to be smaller diameter and wrong shape) are intended as cosmetic accessories - being a very close approximation to the original style, but happen to have the advantage of being capable of use.
Sam - the brackets are very scarce and I've only come across one original extinguisher for sale, and that was in USA (hence these look-alikes).
