Gemini Scrambler? SST? Maverick?

Just bought this bike. It looks a lot like the SST 50cc I had as a kid but may be closer to a Maverick. However, it has "Scrambler" on the tank? I didn't know any of the Scramblers had this type of engine. I think it is a 1970 based on the number on the engine. Can anyone fill in the blanks for me?
