I know the german jaegar rifles are of a shorter barrel usually less than 38" (yes I know germans also had long barrel muskets). So I guess you could say I looking to do more a full stock longrifle (42"-44" bbl) like the pennsylvania longrifle but a blend of a german style such as a little thicker stock and more pronounced, maybe stepped cheek piece. Adding in the fancier germanic furniture. I'm not sure about wood species for the stock but I'd use a chamber's early germanic lock, double set triggers, swamped bbl, and wooden patch box. The buttplate, side plate, rod thimble, thumb plate, and triggerguard will be more germanic style. In my head it seems plausible that the early gunsmiths would have started adopting the longer barrel (to make colonial buyers happy maybe?) and used imported german parts. Do this seem plausible?
Frozen Run: The furniture on that rifle is what I'm looking to do except with a one piece side plate. Just add a longer barrel and stock and it would be just about what I had in mind.
