Reading coil numbers such as AE-22-1200-1

In a number like AE-22-1200-1, AE is the coil form (frame) size, 22 the wire gauge (higher is thinner, more resistance, weaker), 1200 the number of turns (fewer is stronger), and an optional -1 marks a lug or sleeve variant. EM flipper coils use a size letter plus two gauge-turns pairs, one per winding. Gottlieb mostly used arbitrary numbers (such as A-5141) that say nothing about the winding.
