Howdn WRV 204 Compressor parts Drawing needed

Dear Sir,
I have a Howden twin screw compressor, WRV 204 to be overhauled,
I only have the service manual, but don't have drawing of the compressor,
could anyone in this forum kindly help on providing it to me?
the compressor actually is used on a FES 235S plant.
Any help will be much appreciated,

Tung,
To my knowledge there is no parts drawing.
There are 2 versions of WRV204 manuals, I will send you both, as there is old thrust bearing arrangement
like in WRV255 & newer version same as WRV163.
Parts list in "0" ring & fastener kit identifies where part goes
