Hi all, I'm new to these forums and just started to collect and restore old pressure lanterns this year. Most have been Colemans, but recently we found this old, possibly 1920's, pressure lantern up in Wisconsin. From researching pictures and forum posts online it seems to be a Radiolite lantern, however the only Radiolite lantern we've been able to find information on is the Radiolite model-15, which does not have the internal pump mechanism you can see present in this lantern. It still has the same conspicuous mixing chamber and double valve system, as well as a vintage mica chimney, yet this one prominent difference is stumping us. I'm assuming it's a later model made by the same company as the Radiolite-15, but I'm looking for any help in identifying exactly what lantern that may be. Any help or information would be appreciated, thank you!
Welcome aboard! A lucky find and it's probably a later version. 1920s Radiolite 15 Ca 1920 Ulfers Mfg. Co. 4A table lamp
