Hi! Thanks for the help! I found a Coleman pressure lamp today. It was $35 USD (26.92 GBP). Too good to pass up at that price. I have done nothing to the lamp besides take pictures. The lamp does not have a pressure pump. The device which holds the globe looks similar to the 1938 Coleman Canada 154. The original color of the lamp appears to be off-white or yellow as seen on the bottom of the tank (a previous owner removed the paint at some point). Given this color the lamp looks similar to 1939 March 134A with Original Parchment Shade. The lamp also looks like the 1935 Jan. Coleman 134G. There is a "7 8" on the bottom of the lamp that may be of help in identification. I took many pics of the bottom and these came out the best.
