Found this (Alcohol) 340 from 1943 a couple of months back. As with the 341 - It requires only a low pressure to get going. It came with the original paper work as well. (Uploaded in the manual forum). It comes with the Primus 3025 burner. My guess is, that this have only been lit a few times. (Box needs a cleaning)
@BagheeraNZ Thanks - Its more like an Alcohol version of the 210-sized stoves. Thank you Tony and Ken.
Nice! I too have an alco version of the 210, but it has the earlier burner and marked with a sign saying alcohole (in swedish "Alkohol)- nice to see yours with the alocholburner!
@tretrop also a riser from 51/54 is good for this set up, allowing the mounting of the full size 3025 burner. Nicola
