Hi
i am trying to scratchbuild the drivers bay for a dml zsu 23 4m.
My question referes to the two compressor ? tanks to the keft hand side. Look to be yellow, the smaller one, superimposed above a larger grey tank.
can anyone tell me what they are/for and what is the cyrilic name / code on the larger tank.
Thanks

Compressed air tanks are used to start the engine when the starter is not working.

thanks Juhász

Very useful photos from a very detailed build. Could you clarify if both tanks are compressed air or is one, the yellow one a fire suppression system?
From other vague references there are blue tubing which I presume is air from the bottom tank and yellow, matching the top tank.

The yellow belongs to the fuel gauge system , the black reservoir of compressed air starting.
