Calor gas heater with gas cylinder (Beckenham BR3)

I'm offering 2 x calor gas heaters, each with a gas cylinder.

I can't comment on the condition of the heaters - they've been in storage for a long time, and I haven't tried using them. They both look to be in a good state, though a little dusty.

I think the gas bottles are probably both fairly full, as they feel heavy.

One heater is an Alvima Double E, and the other is a Super Ser.
