I'm in need of a complete radiator for a 1550 Oliver, built in 1966, gas, serial no. 255-11032 169 495-504.  Tank on current radiator is not in very good condition, so is not recommended to recore.  Am not having any luck in locating one.  Did the radiator from another model also fit a 1550?
Any advice/suggestions would be appreciated.
Thanks.
Russ
