Can anyone help me identify this? I just acquired this very old camp stove with the inside labels painted over & nothing stamped in the case except the # 209 on a riveted tin tag on the front. It looks & describes just like a pre-1934 3-burner Prentiss Wabers Model 168 I saw here (or somewhere). The grill is cast iron & maybe the burners too. I got it to pressurize enough to emit a little gas, but pump cup needs serviced to get full pressure, so I didn't try to light it yet. It's in fairly good shape except the silver paint-over on the inside. not sure if the red on the outside is original, but may not be because I see dull greenish paint or primer where it's peeling, but it looks "factory" compared to the inside? Can't find ANYTHING on it ANYWHERE, so THANKS MUCH in advance for any expert info.
