Lister 3500208TS1 gen set

[reddmpayne]

I am looking for a schematic for an old Lister gen set.  The printed portion of I.D. tag is mostly gone, the raised numbers are; 
No.  J757/2
type PC 164A        10         continues
pf .8    1800          60           3
220/127            36.5            40
H
H          36.5           1*42

This appears to be 3ph, however the breaker only has two legs ??     mike    reddmpayne@aol.com
