Masport M3 who knows about these

[SadSams]

Just picked up a Masport M3. No label, so i'm wondering if anybody knows what the cfm rating might be. It has a 3hp motor that drives the pump. My guess is its similar to a Delaval 76. That pump also uses a 3 hp motor. Anything you guys can tell me about this pump would be great.

Sadsams. I think my Massport is an M4. Gonna "google" the CFM rating. If you do a thread search with the word Massport you will find a recent discussion with pictures.
