Cylinder tank or other Underfloor tank of Satko

Hello.

I probably moved my tank reports and called Stako already to get ersat documents, but it's been a while now.

Does anyone happen to drive a gas system and install one or the other of Stako's tanks?

From the cylinder tank I can only read the test number
67R-010103

and from the underfloor tank I only know the size, otherwise I have to completely lower the tank
Diameter 63cm, height 27cm.

Welcome
