I'm an Assistant Scout Master in Boy Scout Troop 180. We have a nice custom box containing three nice "American Camper" Stoves. Problem is none of them have a regulator. We also have a Hillary Model No. 201.727540 Sears, Roebuck and Co. that has the same connection without a regulator. I've searched online and can't seem to find an answer to what we need. Keep finding the standard coleman regulator that is sized smaller so it doesn't fit. So far I have found stoves that resemble what we have with a model number of 1085. I've also found a site with a picture of it as a Coleman 174. Hoping someone here may have the knowlege to guide me. Possibly an adapter to convert to a hose to use a big tank would be good too. I hate to throw these nice stoves away. Thank you in advance.
