[AT] OT Antique Goulds water pump HELP

[charlie hill]

I have a     1940's vintage Goulds piston type water pump.  This is a 
residential style pump.
Does anyone have a source for manuals, downloads, parts, people that restore 
them and have information on them etc.?

Mine is Style #511.25.1
Fig.  1798    and then the # 035.  I can't read the heading before the #035.

The eccentric cam wheel on this one is damaged but repairable but it appears 
to be missing the cam follower that goes between the cam wheel and the 
piston push rod.

Any help would be appreciated.
