I'm entering this Skat Kitty in the OldMiniBikes 2012 Winter Build off. I believe it's a 1965 "C" series. It has the bolt on jack shaft and drum brake. I "picked" this bike out of a shed where it had spent the last 30 or so years. I'm really looking forward to restoring this bike and having it grace my garage (or living room) for years to come.
