Soviet Lighter?

[Vorvolakas]

I recently purchased some "trench art" lighters from a fellow in Connecticut. Most of them are your everyday spent shell lighters but this on looks almost like a Zippo. I find it hard to believe the lighter itself was made by a soldier, perhaps a factory worker. There is however some sort of insignia on the front of it I don't recognize. Any input would be great.

Also, the inner part will not come free from the shell, what would be a good way to break this free?

I would guess Air Force, but am not certain.

The cypher is Communications and Signals - from the mid 1930s until the end...

The lighter seems to be a handmade piece by a soldier with some free time and a lack of dry matches, which the latter, IMO, was a very common thing.

I like it very much.

I would just let it be - Display and enjoy it.
