I see both a Primus Model 50 and 51 listed in the literature, and have the Model 51. Both appear to have the roarer burner, and from the photos appear the same. Are there any major differences between the two? Heighth wise would they make a good match to put under each end of a long griddle?
Same stove, different manufacturing material. The No.50 has a tank made of steel, the No.51 is made of brass.
