I Picked up this model 2021 istove recently had a flea market. It is in really nice condition and has its original box and paperwork. I haven’t been able to find out much information on it; but I did have one collector suggest it may have been made in the late 1940s. Seems like there are tons of variations of these AGM stoves. Especially a lot of decaf variations. Lots of different names and sometimes combinations of names. AGM, Scotsman, sun flame, Kamp Kook. This one is an American gas machines sun flame camp cook model 2021. Thanks! Any help would be appreciated.
