Cine 60 base for Arriflex II

[Clive Alex]

I've had a Cine 60 flat base sitting around and after buying an Arri II thought I'd make good use of it. I've never used the Cine 60 base and thought it would be a simple affair of unscrewing the Arri's hand motor grip and attaching the base, but when I removed the motor grip I find two cogs on the Arri's body and only one cog fitting on the Cine 60 base?

You have to remove one cogwheel from the body. It has two small alignment pins.
