I figured I'd post my reply for all to see:
Christopher,
I had printed your address label and was about to box up the module when I decided to wait a couple weeks: I just noticed that my 3W module has one of those removable springs that allow a Wolf Eyes lamp assembly to work in a Surefire body. This is the only such spring I own, and since I'm starting to test Wolf Eyes amps for a review, I'll be needing it to compare various lamps side by side.
So KE7AYF, if you're "in," please don't send your light till, say, March 20, to give me time to complete my tests before shipping my module to Christopher.
