Hello. I'd like to know about the lantern that attaches to the Radius stove tank. I've heard that the 121 and 123 attachments from the early 1930s have different vaporizers than the 132 and 141 from the late 1930s. Is this information incorrect? Thanks to the CPL folks, I'm able to view parts lists for the 132 and 141, but I've never seen a parts list for the 121 or 123, which is why I wanted to ask.
