Question for experts in Russian stoves. (Shmel)

Probably an insignificant detail, but for me it's a bit intriguing.
Has anyone encountered a pressure valve on a Shmel 2 stove like the one in the photo? ( I am referring to the hexagonal nut).
Also the paint color of the tank ( olive) is for me , not seen before.
I scrolled through the entire gallery and did not encounter anything like th is.

 

@Knee No to the hexagonal head of the pressure release valve component, I’ve not seen that. Only the slotted head. A bit off-perpendicular to the tank on mine, but works.




I’ve seen that colour before, maybe not on CCS but in an online auction. The seller had a few and (rightly or not) said they were miliary issue.

Thanks John @presscall . This head is indeed unusual. Surely it doesn't affect the operation of the SRV. Maybe unscrewing is easier ?
As for the color, I also had associations with the military. Maybe there is something to it. By the way, I have noticed that things( not necessarily stoves) with a military past at auctions have higher prices. Some sellers add "military" to the description, although sometimes it has no connection.
Greetings.

 

@Knee You’re right about the use of ‘military’ when not relevant.

Regarding that hex cap screw, it has no gas exit hole in it and the housing tube on the tank appears in your photo not to have the usual holes, but does it? Must have, or the valve wouldn’t function.

 

@presscall . The hole in that photo is not visible, but it is there. I apologize for the not very detailed ( misleading) photo.

 

Ah, right.

 

Hi @Knee

Could it be homemade - after the original screw might have gone missing?

 

Hi @Harder D. Soerensen . This is quite likely. If one had lathe skills.
The one in the photo on the right, is from another Shmel 2.

 

When I get older - I want a small lathe and the skills to operate it :-)

 

it was a usual practice in USSR to make spares on cnc machines more technological. as you can see there was a key for shmel-2 made with special wrench window for it. firstly made for jet replacing, it can be used for safety valve also. very convenient practically.

see also https://www.drive2.ru/b/495122731444994255/?page=0 evolution of shmel's keys.

 

feel free to use Russian sector of internet resources to find any information about USSR made stoves

 

Thanks @gideon . This is very good information!
I bought this one without a key, hence the question.
I didn't know there were so many modifications over the years..

@Knee you're welcome, you always can ask me. i was working at the plant producing that stoves.

 

Have a new to me PT 2 Ogonek and have been watching different videos and have noticed the PIP holder is hexagonal shape on several Russian stoves also. Holds a normal looking circular PIP inside.

 

@Daryl it's a shmel's jet was used when the original holder is missed because it have the same thread - M8*0.75

 

My Schmel 4 has a similar coloured tank.
