Optimus Trapper 81 .. This version being without the small chained fill level plug on the side .
Trapper did never have a side filling, just like Trangia and Optimus spiritburners it fills from the top.
What he means is the "overfill protection" that was added to later models.
Basically a threaded pop-rivet with a threaded plug in it. You take it out when filling, and any surplus fuel comes out through the side. Sorry for the less than perfect picture.
I've just found one of these at the back of a cupboard in our scout hut. Unfortunately the burner tube is completely empty with no sign of any mesh, material or any of the plastic bits. Any idea if it can be repaired? Oh and to make life interesting I'm in the UK.
Hi, This may help you see how it works, the fuel tube should be empty. You need the red tube part to fill the stove. Inside the stove is a fibre glass like insulation. You can feel it if you put you finger down the hole. The other plastic part is a measuring cup, you do not want to overfill this stove.
A&H pack stoves in the US may have what you need.

Thanks for the reply. When I said the tube was empty, I meant empty. All the way down to the adjuster plate (see pic below, the adjuster is 1/2 open). the fibre has long gone which is why I wondered if it could be repaired. The site you mentioned doesn't have the parts listed unfortunately.
That tube is meant to be empty. The fibre is in the inner walls around that pipe.
When you fill the stove the safefill tube basically blocks the hole at the bottom of the tube to allow meths to flow into that fibre.
A&H pack stoves had the parts you wanted on ebay for a long time so it can't hurt to email them.
Right, I see how it works now.
