There was a version of the Harper's Ferry 1805 imported in the 1970' and 1980's NOT made by Pedersoli. Some appear to be Belgian.
They had lock geometry problems on the cock and frizzen interaction, and generally mediocre quality.
If it doesn't say "Pedersoli" on the barrel, I'd avoid it. Pedersoli marked 1805's get decent reviews from their owners on flint life, and good sparking. Why they continue to made with 58 cal rifled barrels is unclear, since the originals were 54 cal smooth bores.
I suppose someone could defarb a Pedersoli and remove the markings, but why go to that effort for the wrong caliber?
