I believe they are old NY rifle boxes. The first style you show, with the double-pierced finial, is known to have been used on NY rifles, though not necessarily cast. I'm thinking they may be from the very late flintlock period into the early percussion period. There was a good deal of industry & trade going on in NY, esp. around the time of the Erie canal. J.P.Moore was from NYC iirc. The rifles shown by others may be from NY, esp. the caplock.
