Our museum was recently gifted a Witte BDREA from the 1940's. We would love to restore this wonderful machine and use it for demonstrations during tours and our annual fall festival. However, we are finding the fuel pump is needing replaced and have come to a roadblock in locating a replacement part. It currently has a Lister Eccentric Fuel Pump part # 47-103-410 (according to the invoice) that was put on in 1980 (again according to the invoice). If anyone can point me in the direction of someone I could contact for a compatible replacement part I would be very appreciative.
