Can any body tell me what the difference an Optimus 200 and an Optimus 200P is? Were they both made at same time? I'v been a stovie for some time, and have used pressure lamps for almost all of my life (all of them Colemans). But at last I been bitten by the pressure lamp collecting bug. We'll see were this take me. Rick
Hi Rick We have had a bit of a discussion about the difference between a 200 and 200P (see [url=http://0flo.com/index.php?threads/456 ). The 200P came after the 200 and the change occured some time around 1950, probably before. I'm still looking for conclusive proof af the differences. Any information for the 200 / 200P is also relelvant for the 300 / 300P.
Most but not all of the 200P appear to have been "accessorized" with a fount mounted manometer and fuel level indicator. They use a fuel cap with a pressure relief valve. The 200 has none of this, just a petromax style fuel cap with integral manometer and pressure release screw. Of course, like the 1200, there are many exceptions. Dan MacPherson
There were a "200" and "1200" made in the 1970s, I think, that were identical to the 200P of the time. I am sure these were for the Swedish military only and have only been seen since the military started selling off their equipment. Whether they were incorrect stampings or on purpose is not known.
