Some of you may well have seen this one join my collection last year at Newark. I've not yet tried to light it, but I see no reason why it wouldn't work. I know of 3 including this one and the 500cp version shown in the gallery, I'm sure there are more lurking in collections though. Anyone got any thoughts on why the Tilley logo on the underside of the reflector is upside down? It's the same on the others too, seems odd.
