Welcome to MLMF josh35. Those old Eclipse mowers were made to last.
If you'd like, I can get you a pdf of the parts list for the Rocket, if you don't already have one.
Sadly, this is all there is of the original building in Prophetstown, IL where they were made, but some of the other buildings that were built as the company grew are still there, used for other things now. The historical society in Prophetstown has some information about the company, but old timers in the area have more, if you can find them.
