Hi,
I got this with a bunch of other parts. The top tank is brass, with a brass spout. The sides look like steel. It is a low radiator, no maker's plaque.
Is it a bog standard low radiator, or an 'old' one? I suspect it is a plain one, as the front of the tank has those stiffening watchamacallits. But a guy can hope.
Cheers,
