Howe Discharge Valves

Good Morning. We have a number of Howe boost compressors and the availability of repair parts from them is steadily declining. Has anyone had any success in locating another vendor that may have NOS or aftermarket parts? I'm looking for some discharge valve plates for a J56BN. Any insight you could provide would be very helpful and appreciated!

Have sent you a PM with a contact. They still work on old machines on occasion.

Thank you NH3LVR, I was also able to track down the company that supplies the valve parts to Howe. It is actually a Hoerbiger valve and their part numbers are stamped on most of the parts!
