John, I do have new Franzite BPBs that closely resemble the original Mauser bottom, but with only one hole drilled, so you will have to drill the front one, @$15 + $3 S&H. I will be introducing some perfectly made repro BPBs for the center pinned FXO mags at the Louisville show the end of this month. Introductry price drilled with pin @$35 or undrilled, if you have a drill press and perfer to "do it yourself" @$30. Please send MO or check to Tom Heller POB 398 St.Charles, MO. 63302.
