Thanks Chuck. I just found the 27th Ed for 14.50...I've seen that you and some of the other metal guys use it as a reference. One of these days/weeks/years I'll get to my experimental stripping of the Citori triggerguard. One of the internet guys said he stripped it with 30% hydrogen peroxide. I've got the electoless nickel stripper and that was plan A, but that was 14 months ago.
