No name kerosene stove small silent burner

I bought two random stoves today. One of them has no logo. But it has decorative legs and a very nice silent burner. What to think about it?

 

No clue what it is, but it looks awesome.

Some photos of burner

 

That's a really beautiful burner. Much better looking than most. Seems like a rare find too

 

I got no idea how to fix this piston ‍♂️, of course the gasket was in the cylinder, it has already been removed. The large nut and the ring fly freely on the rod, the small nut stays on top of the rod.

 

This is a check valve
It closes on the cone of the core
On the move to the reservoir
It loosens when taking in air

(To jest zawór zwrotny
Zamyka się na stoźku rdzenia
Przy ruchu do zbiornika
Luzuje przy nabieraniu powietrza)

 

The leather pump cup goes between the round brass piece and the steel hex nut. The round brass piece goes inside the cup.

When the pump cup is installed properly, it slides up and down the steel shaft a bit, this allows air to flow through on the return stroke. It should not be firmly fixed in place.

 

I don't know, don't you know how to sequence it?
If that's what you mean, that's the order.

 

Thanks for your help, gentlemen. The surface of the cone on the rod was not smooth and did not seal. I polished the cooperating elements with polishing paste and it caught tightness. The pump needs quick movements. I made a gasket and assembled it. Well, it turned out that it pumps, but the tank does not hold tightness ... I made a gasket for the filler cup and screwed the burner with Teflon tape. And I started looking for leaks with soapy water. Unfortunately I found this ‍♂️

 

It'll be tricky, but even that crack can still be fixed!

 

After a quick and ugly soldering, the burner works. But the flame is kind of orange.



Ok is alredy blue.

 

You dealt with it quickly!
Could you show a photo of the soldered crack? I have one tank with a similar crack, but I am waiting for now. What kind of solder did you use?

 

I'm a hothead Now I can't take a picture but it's ugly, I used 3 types of tin, rosin and then flux paste for electronics Tin didn't want to hold on. After some time, I managed to fill the crack, but quite thickly. I'm afraid it will crack when sanded. Apparently I should use a specialized flux for brass...
