Main hydraulic Cylinder for Semad Simply Air Operated Coil Spring Compressor.

There is only one version of the SIMPLY HERCULES line (both 9903 and 9905) that requires a Cylinder Replacement of a different type, but it is a very rare model and in any case dates back to the year 2017, therefore please provide for the Serial Numebr and Year of Construction of the unit that needs a replacement before ordering.
