I have recently found a Bialaddin 300X which I found at a car boot sale and managed to buy for £12.00, I think that I now have enough Tilley's in my collection! Hopefully someone may be able to answer my questions here.... I am guessing that this lantern would date from the early 1950's? Being a bit of a purist I am interested that the tank has a small one inch filler cap - on every other 300X that I have looked at on this site is this in fact correct? It does not look in too bad a condition overall so will give it a bit of a polish up. Also does anyone know what is the nearest colour of green for the tank? It almost looks like an early Land Rover green! Many thanks.
