I have two Rayo Hot blast lanterns. Both have patent dates of Apr-10-06 they are identical except for the model number. One is a #75 and the other is a #90. These lanterns are the same right down to the brass burners and fuel caps.
Now I just picked up a third Rayo hot blast and its also a #75 but there are slight differences in the construction and no brass, just tin burner and fuel cap. Can anyone explain why Rayo numbers there lanterns like this? I've just started to collect Rayo's so any info would be helpful.
