Problem solved.
Next problem to solve: Who can complete/finish my flintlock parts [and??] render everything into my rifles? I typed "rifles" as a plural because the goal is to have two .72-caliber flintlock rifles, not just one.
As I type, my thought is to have one rifle emulate the configuration of one of the M1803 Harpers Ferry rifle variations, the other to be full stocked, perhaps similar to Baker or Jäger configuration. I'm just so happy to be off the dime, I haven't given finished configurations nearly the thought it deserves.
