Kalvin,
Your grip looks to have only one hole for an attachment prong. I've seen 2, 3 and 4 as well. Make sure your grip emblem similarly has only one attachment prong, it will make things easier when adding the new grip eagle. Manfred is certainly the man for the job, I'm having do one for me as well.
Tough to say regarding value. Considering the piece's condition and the fact it's missing the clamshell and grip emblem, I would estimate a guess at $750.
Joe,
I believe Kalvin's piece was privately purchased and would have no issue or accountability numbers. My WKC similarly has no such marking either.
