Interesting lamps, the CQ series. I have a 1919-22 model with fiber valve control wheel and some in late 20s with 12 ridges made from Bakelite. Interesting too, the date of Bakelite on the 1926 as that is I think, an early use of Bakelite. Anyway, I am really interested in the CQ from what I believe is 1922-23 as I cannot find when that wheel appears. I thought I may have swapped it and the entire burner from a PQ chandelier but I am inclined to think not. Here are the 4 wheels: 1919-22 (L) 1922-23 (Middle) 1926 Canada (R) 1929 All are marked with CLOSE and the arrow but the 1922-23 CQ valve control wheel is the one I am curious about. Hoping a Coleman fan can help tell me if it is correct. Interestingly too is the 1929 Model C has a nut retaining the top of the handle and from the Coleman book it would seem by then it should have been a round threaded sleeve. The 1919-22 CQ is also interesting as the Burner caps have straight sides for tying the mantle on and the later models all have a slightly concave shape at the same location. The 1919-22 CQ figure 8 casting (part Q17) is also different to the later ones as it has two angled edges rather than an almost straight side. Iain
Lain I'm certainly no expert on the valve wheels, but from my examples your 19-22 valve wheel is correct. The there were strait sided fiber wheels that predate yours without the close with an arrow, but I don't remember how long they were used... Only a couple years starting in 1918 if I remember correctly. Then the one you have pictured until 22. Then the same style fiber wheel would be found with a letter stamp starting with A in 1922 and B in 23 and so on ending in letter G for 1928 when the bakelite wheels started showing up as well. Your second picture appears to be from a Canadian model of which I am no help.
Thanks Toby, the 1926 is the only Canadian model. I say that on the basis that the fount for the 1922/23 is unmarked but the handle indicates USA. also the Canadian ones seemingly were all stamped with logo from the beginning. So this 1922/23 unit’s valve wheel seems odd, but maybe it’s not; I don’t know. I cannot see a letter on it though.
Lain pardon me as I'm easily confused and it's still early here yet if I understand you correctly you are curious about your CQ that you believe to be a US fount, but possibly has the Canadian valve wheel? I've probably got it all wrong Pictures of your lamp and it's features may help narrow down your suspicions. Keep in mind these fiber valve wheels were often damaged and replaced with newer bakelite wheels, or just replaced with one from a parts lamp that was laying around.
/////////::::::::::::::........... Toronto lamps and lanterns did not have letter stamp (date) on their fiber valve wheels at any time, only US versions. 1928 was the transitional year for the bakelite valve wheel in the US, as some earlier production have fiber valve wheel with letter stamp “G” and later months have bakelite.

@coleman54 @Toby Garner Thanks Larry and Toby for the information. I am currently on a Coleman drill down on what I have and the differences with these early Colemans, both your posts (and the one the other day Toby) have helped me a lot. I think Toby your comments even early in the day are more accurate than mine and any confusion in my post is regretted. I do think you are right in that the valve wheel is a ring-in from later. Not sure though what it's off but I will keep looking. They are beautiful lamps and I will keep fettling and thanks Pete ( @AussiePete ) for the link. Iain
