Hi. A friend is cleaning out a house and came across this Trangia and unknown burner. Not sure of the age but my guess is 80's or 90's. The hose feels really good and not at all stiff like newer ones. This is old school heavy duty rubber. There's a butterfly symbol on the top which I might recognize but can't recall from where. If anyone should know anything more about this curious burner I'd love to hear it.
