Here's a Svea 5, identified by some members of this forum as being of the latest ones. 1950's maybe. The NRV has a plastic seal and no metal spacer. The pan holder is stamped steel. Do to size and weight I use it only indoors, just to add some pleasure to the morning coffee and slow-down the routine a bit It's my only classic stove (so far...) I now usually run it without the igniter tube, that is neither really efficient nor really necessary.
