The Brown Bess musket parts sets with the unfinished, new stocks are selling very well for them. They need some work (trigger and triggerguard pins are way off and need to be repositioned, easily done) but altogether they are interesting. The "Nepal Cache" guns are selling hand over fist and with new shipments, the prices keep rising. I have seen some of the restoration work on various Forums, some good and some bad, but many people are getting some pretty good examples of some unusual and rare guns under the hardened grease and dirt.
Still, for those of us that love military muskets and rifles it is tempting. The pre 1853 muzzleloaders that are Nepalese made were almost unknown until IMA brought these into Europe and America. As I understand it, the Nepalese armorers were trained by British Ordnance and their work, including barrels, is not bad.
