Bunch of old Soviet junk movements

[Terrinecold]

I got these from eBay to practice disassembling cleaning and reassembling movements without ruining working ones. 
I had the hopes that at least one could be made from the parts which would live a bit

so in the whole lot, I only found two which had balances which would oscillate. Both have damaged hairsprings, but not as bad as some of the others. 
One of those is one of the four movements at the bottom.

None of those four movements seem to have a cannon pinion. In addition I do not have a stem for any of those movements.

So after more careful examination, I have no hope to make a working movement out of it, but I hope I can still gain some knowledge from practicing.

Those movement have a double barrel must be pretty common since four of them were included in the lot.

Does anybody have any idea about what they are? I will take pictures as I disassemble them.  Maybe there will be some indication.

Sorry for not having more pictures yet. I am taking them with the camera on the microscope. I do not have an easy way to read the SD card yet, reader is on the way and should arrive today.

Think most if not all are Slava movements.

The ones with 2 mainsprings are possibly 2414s

Most if not all parts are available for these from Cousins, including complete balances.

One of them has the number 2414 on it so that is what it is. As I am disassembling the two in best condition.  There are things that confuses me of course being a beginner I am easily confused. But in particular the gear train seems to have too many wheels. The whining works. I am used to having the crown wheel with a small internal ring. In this movement, it has that, but there are two other wheels between the crown wheel and the ratchet wheel which also have internal rings.

Until I can retrieve the pictures from the as card here is the result of disassembly of 2 of those 2414 movements. 
None of them have a date dial or the cover, which is supposed to go over it. 

Next step will be a much needed cleaning. As you could see from the pictures these were filthy

After cleaning when I tried to rebuild at least one movement out of those two I couldn't successfully oil the capstones.

Specifically I couldn't put back the shock spring (not sure what is the name of that pattern) I lost 3 and broke 2 (I kept cannibalizing the other movements in this lot).

I ended up giving up.  I'll start another project as I feel like there is little chance to make one working movements out of those and they are so filthy It is a huge amount of work just to clean them.  Then there is the complexity with keeping track of which of the very varied screw go where without technical sheets.

Those springs are not the easiest to deal with for beginners. How are you cleaning them and what with ? 

[Terrinecold]

I cleaned the balance and pallet fork with hexane and a brush as well as peg wood for the spring.

The spring which were on the main plate went into the regular cleaning:

• ultrasonic in lighter fluid for wash
• ultrasonic in lighter fluid for rinse 1
• ultrasonic in IPA for rinse 2
• Dried out with hair drier

But the movements in this case were really unbelievably dirty.  I'll add picture today or tomorrow when I have my sd card reader and can extract them from the microscope camera.  Like if they had spent some time buried in the woods outside of a case so I am not sure that learning to clean such is really actively useful.
