So, this is not the old style, it's the new style. I've yet to use this beyond verifying that it spins a socket and has more torque than I can hold back with my gloved hand wrapped around a 36mm impact socket.
There is a light but thorough coating of grease on the hammers, hammer cage and the inside of the housing. I hope that the pics are clear enough, if not I can host them elsewhere.
The pics are great - THANK YOU Sir !
