Maybe something like Track's "Jacob Dickert" kit, if you can get it without a pre-carved lock mortise.
American longrifle: Jacob Dickert - Lancaster, Pennsylvania - Track of the Wolf If you had a Track Of the Wolf catalog, you could compare your Pedersoli lock to a Large Siler Lock, to see if they'd interchange.
That way if anything ever happened to your Pedersoli lock and it needed replaced, you could just drop a "Large Siler" in, drill for new lock-bolt, and you'd be back in business.
Which reminds me,... those lock-bolt threads in your Pedersoli lock, are "METRIC". :rt th
Also,.... if you feel a bit intimidated about inletting the kit's patch box, you don't HAVE to put a patch box on the rifle, just because Track lists it among their parts.
Track'll also "breech" the barrel for you, as well as cut dove-tails for sights and under-lugs,... all for an additional price of course.
Track's "kits" ain't really "KITS" when compared to such kits as Lyman, CVA, Traditions, and etc.,.... Track's kits are more a "compilation of domestic-made parts" that you can build a very fine gun out of.
