According to the Radius parts lists, the mica cylinder was offered as an alternative. The glass had part number 102/24 and the mica part number...
Not so easy as there is a metal shaft involved. Here you can see a picture of mine showing the wheel and shaft. It is the later version with...
@presscall What do you do with the inside end of the needle (in the jet)? You have to avoid an edge that the cleaning needle can catch on.
Another collector here in Denmark had the top cap pop off with a bang while the lantern was running. It had just been cleaned before being used....
You can get new pips for the NRV from the fettlebox. It is quite likely that a later lantern has a fully moulded pip and no brass cup. These are...
A 500cp jet should be part number 2672. The needle is correct with 2682. 2621 is the bottom valve or fuel feed valve seal. If the picture is...
That helped to get the 155 link. I can see that 2365 is in a 1979 price list but not in one from 1985. Unfortunately I don't have any price lists...
In all the Optimus catalogues I have, the NRV is listed as part number 262 in the old numbering scheme and 2250 in the new numbering scheme. The...
Running the lamp wouldn't get it hot enough. It works best to heat to a dull red and then into water straight away. The screw holding the J tube...
I have never had to do it myself, but would probably end up trying heat and quench. The ceramic flame spreader probably wouldn't survive, but it...
That's a very good find and in good condition too. As has been mentioned in other posts, there were two styles of filler caps. One with the pump...
Good to see another one. There don't seem to be many around. Could you take a photo of the back of the tank? Mine has had some serious repairs...
What I mean is that the valve in the pump tube (the non return valve NRV) is all that stops the fuel from coming out. On other petrol fueled lamps...
Nice find. The 300B is not that common. The one I have has had a kerosene jet fitted and runs on kerosene. I'm not a fan of the pump not having a...
Nice find Frederik. That looks to be in good condition and working well. Is it just my eyes or is the top cap a different green to the rest of...
If your unsure about how the rubber reacts to kero, cut off a small piece and put it in a small jar with kero for a few days. If it swells at all...
Interesting how you made a heat shield. I am missing a couple of them myself. Just for info. The thread for the retaining screw is 5/32 W.
