what is SW?

Greerting to you, too!

SW is strike weight, the weight of the hammer and shank as a horizontal lever, supported at the center pin, weighed at the center line of the hammer molding.  Sometimes this means the SW of a single hammer, sometimes the overall SW of the full set.
See David Stanwood's articles and web site.  Or maybe better to read and digest Bill Spurlock's article (Grand Action Touchweight) on his web site first.
