late production - witout "Made in GDR"... Please - Check magnet bottom of the tank... The beatifull brass tank bottom could be iron/brass platted. But what's going on? The iron/brass bottom with brass top - gives You new possibility... You have "2 in 1" - stove (may be yet) - and cu fe galvanic cell I am very sorry - Chief Engineer forgot to design the contacts... Yours 0,43 V - are not for You. But rust, willing to use it. Iron is reduced and left only a brass film. Several times used , almost new - left for a couple of years - they are good for nothing . Convey my greetings - and recall of the outstanding classes of electrochemistry.
Rust and tank splitting. Two bads don't make a stove right. Wow. That's very bad. It 'looks' like brass, maybe even 'smells' like brass, it 'feels' like brass. Good thing you didn't step in it. sam
on photo "burner mounts" - You see hole in fuel pipes, thats was concret piece of metall... I Cant imagine myself - what kinds of knowlege they use to produce THIS. Stove has less then 25 years old. Was destroyed by time not by the exploatation.
Hi Georgi, following your invaluable hint, I checked the bottom of my 2-pinter BAT and found it to be non-magnetic! (big sigh of relieve... ). Mine is the "N°5" type of stove with fixed legs. Best regards, Wim
I've noticed that the BAT petrol stoves can also suffer badly from rust. Something of a challenge finding one that's not alive with tin worm. I had a Coleman 500 given to me for spares, the steel base of the tank rotten. I never could understand why Coleman made the rest of the fuel tank out of brass and just the base in steel. Stiffness possibly? John
Thanks for this - about two weeks ago I bought an unfired 2 pint BAT. Guess what, it has a steel base - guess it will definitely remain unfired now. Norm
look inside with a torch. If its not rusty get one of those fuel tank repair goos and coat the inside. Problem gone
Just a question: how can a steel/iron tank corrode like are showing us, when it is only in contact with paraffin? Should rather act as a corrosion inhibitor, shouldn't it? Regards, Philipp
Tank always contains air. Air contains water. Water settles out of air and collects at bottom of tank. Right where the steel is. When you pump a stove you put more moisture into the tank. There has been discussion here more than once about the benefits of storing stoves empty. For stoves like this it could be a very good idea
The next trap: Juwel 34 - circa 1956, optical as new, full set. but used. after 5 min perfect work lost compresion ->under the paint vast holes. Original paint need to be removed, hard welded. Working good - now. ------- First look - condition, in steel tanks - is often misleading.
George and all This discovery is very important. Many of the BAT tanks that look brass are (partly)made of tin. Make the magnet test. I did and and by good fortune mine are brass. But with the spirit BATs it is the same. Only the early ones are fittet with brass tanks. This problem can also occur with the "Abeille" stoves-said to be French- and the "BEE" - UK & US market-(https://register.dpma.de/DPMAregister/marke/register/DD631531/DE). They all were produced by BAT post June 1963.! Peter
