Just brought this one home today and can’t see a model number on it. Year 1937, can’t see the month. Could it be a 427K Mountie?
I agree that it's a 427 but the vent looks more Canadian because of the "seafoam" color. The top portion of the vent looks pointier, which is typical on Canadian quicklites.
From distant memory of my pair of Mounties, there are two dimples on the air intake (?) which fix an air restrictor in place. I had no clue what my lanterns were until Neil identified them by the dimples... Coleman twin mantle paraffin/kerosene burner. | Classic Pressure Lamps & Heaters and scroll down...
Thanks all. Sorry, should have said Made in Canada @Tony Press and @rr_res and I have found a dimple on the air intake tube. Assume the second is hidden. Not a very common lamp then? I’ll put a pic in the gallery before I try to clean it up a bit.
