Not really LBC, Radiator cap help needed

["Stephen Hanselman" <tr6@kc4sw.com>]

My dad has an old (WWII) vintage Onan generator. It has a convection
driven water cooling system.  The radiator cap is made mostly of brass,
and appears to be a bit bigger that a "normal" cap, and is beginning to
need replacement

Anybody got an idea of places that might have usable replacements??

Thanks
