Disassembling a CCM Flyer crankset for cleaning and greasing.

I am looking for some guidance in taking apart the crank assembly of a ~1937 CCM Flyer. I do not want to bang or torque in the wrong direction and I can not seem to find a relevent YouTube video. Any suggestions on methodology, tricks of the trade or specialized tools required to accomplish my goal of cleaning and greasing. Thank You.

Hopefully the included pics attached.
