Is that a fact, or just speculations? If so, the other one here shuod be PB - paint-brass? Maybe hard to see on the box, but it says 181 FF
Fantastic stove Could you please provide some more pictures from different angles and showing some more of the details?
Fact - but I'm happy to be corrected! I've never seen them use model coding for the paint or plain brass. But show me the proof from a catalogue stating the p is for paint & the b is for brass & I won't argue with you! What other one? If it's one you have & it is not nickled I would say you have a wrong label - I've seen that before - both completely wrong & also clumsily corrected - ie a Optimus 96 without tin in a carton with 96L label. There was no room for a tin!
The other one in the reference gallery. Looking in the catalogue mentioned above, i can see that one should be either 181 B or 181 EB My PB was only a guess before looking in the cat. Is it japanned or enamelled? /Hans
Certainly at the time of that catalogue the enamel is said to be cream coloured so I'd say it was japanned. I don't know where you get the B from? That catalogue gives 181, 181M, 181F, 181EM, 181EF & 181FF. From memory there were less permutations than that in other catalogues.
OK 181 M it is A bit of shortcircuit language confusion.... Reading M = mässing and then translating to B = Brass - wonder why???? /Hans
