Revell "Visible V8" Model Kit

I had one when I was a kid. It had moving crankshaft with pistons and red lights for "spark plugs'. If I remember correctly there was a transmission and the shifter was the on/off switch. I was probably 6 or 7 when I built mine....with my dads help. I don't remember it being very dificult but then again I don't remember much from 35 years ago....lol.
