How Gottlieb switch blade numbers are laid out
Leaf switch blades for 3/8 in stacks are numbered by thickness and cut. With tail: A-391 to A-395 are 1st cut in .008, .010, .012, .016 and .020 in thickness, and each following group of five (A-396, A-401, A-406, A-411) steps one cut; the 6th cut is A-2314 to A-2318 and the 7th cut A-416 to A-420. Blades without tail run the same way from A-421 (6th cut A-2319 to A-2323, 7th cut A-446 to A-450).
