November 1927 L227 all original with factory mica & captured nut vent. Also a July 1928 with reproduction Mica from Fred and standard ball vent nut. Same burner setup as above. My favorite Coleman model hands down. These will be the last to go. Here's some photos of them together.
@Toby Garner These are very good lanterns, and thanks for the post. Can you explain the “captured nut vent” system, please? How long was it used, and on what lanterns? Cheers Tony
@JEFF JOHNSON thank you Jeff, I agree @Tony Press these were Coleman's first production bighat lantern. Before this Coleman offered the 216-490 bighat accessory vent that could be used on the earlier 327/427s. The accessory vent had a bail attached to it. If you notice on the bottom of the captured nut vent on the outer brim is the indents where the bail was attached as well as some tabs for centering mica for the accessory vent version. I'm not certain why Coleman thought the captured nut was a better idea... Altho with half the lanterns I fettle missing the original I wish they would've stuck with it From the small number of 227 examples I've seen the captured nut seemed to transition away in early 28. Perhaps Larry @coleman54 could offer more info on the history of these.
Hi @Tony Press @Toby Garner , The captive nut was as Toby mentioned first used on the early L227, and a few of the first L228 had them as well. Evidently the captive nut had issues of seizing as several examples found have the inner flanged part separated and usually missing, with the vent suffering some damage around the hole. Larry
@Toby Garner @Tony Press I should have probably mentioned that the L216 of which supposedly there were only three produced likely had captive vent nuts. Sunshine Safety shipped by Coleman also had some of them too. Larry
