Recently acquired this not bad nick Tilley, but apparently not used for a few years, and most of the seals had perished and gummed up! A good clean up, refuel, and replacement washers did the trick! The mantle didn't shape properly, but OK for test purposes........Held pressure nicely! Very pleased with this one, as it's the only Tilley in my collection. Thanks to Jeremy (Broadlander) for his Video, which I had to refer to a couple of times.
