Speedair compressor identification

[Anderson55616]

Got this compressor from a job site. They were about to toss it due to loss of compression. Found all the rings had seized due to a bad check valve letting water seep back into the compressor. After cleaning the bores they seem to be fine. Went to find a data plate to see if rings and bearings were available, but no dice. Data plate had been removed/was never there. There is a separate plate with two numbers that don’t lead me anywhere. If anyone has any knowledge on what this compressor may be please let me know. Thank you.
Numbers on plate: CLS30 GH0103
Numbers on sheave: 01202560A 01201560VA
Body castings: AIM DF

bearings are probably generic, run of the mill. they should have a trade number on them . rings? might be able to source them by bore & measure the width of them
