Is it a RockChucker or a RC II?

[km101]

I have a Rockchucker press that I bought about 1973. It has the screw-in bushing in the frame and originally had the "bicycle grip" handle. I am trying to find out whether it is an original Rockchucker or a Rockchucker II.
Can anyone give me any information as to how to tell the difference? Any help appreciated.

The Rockchucker will just have RC on the side of the press. I believe the Rockchucker 2 says "RCII" on the side.

Thank you sir! I guess it a Rockchucker then. But it has many of the features of the RCII. Must have been a transition model. I have never owned an RCII, so I didn't know about the name difference on the frame. Thanks for the info!
