Craftsman Travelling Sprinkler Parts

These are some replacement parts for an ancient [Craftsman Travelling Sprinkler](https://www.ebay.com/itm/Vintage-Craftsman-Cast-Iron-Tractor-Walking-Lawn-Sprinkler-Hose/173341107623?hash=item285bef65a7:g:BQ0AAOSwIFtZ9RAK:sc:UPSGround!78232!US!-1). So far, only the grub gear and bushing have needed replacing, but some of the other gears will most likely need replacing (so, designing) soon.
