This is my restored (?) Tilley PL55 from, I believe the mid 1930's. It has a brass control knob. It was supposed to have that "lighter" on it but I screwed, the guy I bought it from removed it because someone told him it didn't belong on the lantern! After a lot of screaming and yelling he lowered the price and some postage, too. It came from across the pond. You just can't find them here.
