オプティマス123のからのをさない！な

optimus 123SVEA 123 stoves = 4,700 BTU'd Optimus 8r, and 99 = 3,300 BTU's. My own experience with both stoves seems to easily show the power difference between them. AsPer a 1970s Optimus brochure: the Svea 123 boils 1 liter of water in 6 mins.-----EDIT: well well well credit @Tony Press recently posted c'93 Optimus catalog approximates
