That I don’t know, don’t know who made it and it appears there is quite a bit of rust on the cupping balls that would need a fair bit of work to bring back. You could try and ask on either international waters forum or Jim’s rc boat dock forum....I’m just a run for fun rc boat guy, you need to talk to someone that’s serious about racing (and who mods their own props), may look for a local club in your area as well.
