Imperial Gunnery weapon's guide says, the presence of an EPM on the hilt is also a good indicator. It doesn't say that it is present on all Taiwan sabers, that's what has me mift. Having a lettered hilt on a saber is a good indicator that the saber is authentic but there are alot of authentic sabers out there without lettered hilts. Just wish they'd say all Taiwan sabers have the EPM on the hilt, if that's the case. If anyone out there has pulled an original series Taiwan Luke, Ben or Vader off a card and found that the saber had no EPM on the hilt please let me know. I know it's not a big deal, I can just replace the one I have with a Taiwan with the EPM but this kind of stuff gets under my skin and drives me crazy.
