Very nice. A bit of pendantry here, the correct name for your stove is Model 1942 two-burner. or M1942. Only Coleman called it a 523, that was their internal designation for it. Good to see a war-dated example, they're getting harder to find especially in such good shape.
I do not know how to correct title of tread, if moderator can correct it I have nothing against. It have been a user for years, then seated in a luckily sheltered wood store cabana.
Ciao @orsoorso, you should find 2 cylindrical containers locked below the top plate. They contain spare parts. It’s unfortunate that it doesn’t have its carrying metal case. Nicola
There's also a folding wind screen accessory. I'm not sure if this was available with all stove or just specific year(s) or mfg(Coleman vs AGMco)
