It is a 1994 H3 model. They used to have four silver aluminum blades and the J Models (they came out in 1996) have 6 blades. The very first A models and a few Bs had 3 bladed props. I have never seen a 3 blade prop in person.
These NP-2000 props have 8 blades and are friggin awesome. Between the new props and new Rolls Royce engine upgrades, it is a total sportscar.
You wont see any more of the older 4 blade hurks anymore. The props got old and started having issues like blades coming off inflight. That is not good.
