One of my recent additions. So knowledgeable ones , any clues on a bit of history or year It’s the first 310 I’ve seen with a blue hood , in fact having searched through the lamp reference section on here it’s the first blue hood on a Bialaddin / Vapalux I have seen. Will be cleaned up and resealed , pump does just about work and the tank does hold pressure , so dropped lucky I hope
Search for "Rothmans" here. I don't know which models were specials for Rothmans or how many times they did it.
Understand them to be 320 modes in the 70s and have the later taller chimney style hood and a chrome tank Ian Ashtons lamp from the Gallery Cleaned it up a little , colours are easier to see The tank is a lighter green than my 300X or M305 , red cock control knob and the hood is more vibrant
I used to smoke Rothmans 30 years ago lol, would've loved one of those 320's. Way before my time though. Don't think many exist? Never seen a blue mushroom style hood either though, bit of a rarity I'd say. Happy fettling
