Produced with the earlier burner. Produced from at least 1934 to approximately 1947
I've seen the three differences to the tilley logo or the absence of logo on the reflector.
1. with "Tilley..." on a plate attached to the reflector, like the one in my picture from my collection.
2. with "Tilley ..." stamped in to reflector, like the one pictured in the excerpt from the catalogue.
3. without any logo on the reflector I have seen on some one else's R22 and also one that I have in my collection that has been converted to electricity, (Doh)
This Radiator was produced in Brown seen here, and the much rarer black with the chrome reflector.
