To the boardmembers who have responded so far, thanks for your helpful comments and suggestions. Before I posted this thread, I'd been in touch with Kevin, Andrei, Doug (Tantal) and all the usual suspects, but no PGs are available from these usually good sources at this moment. I was hoping to find someone who had a Russian PG which they had bought over the past few months when they were plentiful, and then decided they no longer needed it. I'm kicking myself for missing out on the 3-piece sets which were available (until about a week before I wanted to order one). I've located all the other wood and it's waiting to be finish-matched, but I'm lacking the PG. No PG=project in limbo. So hopefully, one of you guys who bought a set from Doug at Tantal will decide you like a cheap plastic grip rather than a VERY expensive laminate PG. I will convert your new-but-no-longer-needed Russian laminate fat grip into some nice green cash.:-)
Believe me, no one will be happier than I when I can post pix of the finished restoration. It'll be a bute!
