I'm a member of the Williams Grove Historical Steam Engine Association (WGHSEA), we have a Model 9 Auto Patrol Grader serial # 8-A-157, in good condition except for the intake and exhaust manifolds. It is a Caterpillar 4200 G gasoline engine, also in the Twenty Crawler L& LP series. And help to locate these manifolds would be great appreciated.
I heard about CAT Cave Foundry in England that makes new ones but do not know how to contact them. Thank you
