I have purchased one of their "kits" and although it was not one of the EIC ones per say, it was one of the "temple marked" lock musket kits. What you are getting is an authentic piece of history in untouched condition, with a newly manufactured stock that you will have to make the parts fit into. At the time I bought mine, the did guarantee that the lock would at least function, though it would be absolutely filthy, the only cleaning that would be done to it on their end would be to see if it was "temple marked" or if it was marked with the EIC markings, other than that, it could be stuck frozen, etc, but it was supposed to be complete and functional. How they could know that if it was frozen with crude is beyond me, but if it was not in working condition, you were supposed to send it back WITHOUT working on it for replacement. The barrel could be pitted, rusted full of sand, bugs leaves etc from being stored for 125 plus years. It will come stamped most likely with the two "feet" impression that represented a certain emperor or something, I forget his name, I have the book here. You can see where the barrel was forged by twisting the iron bands on a mandrel, think of a candy cane appearance, very nice looking once cleaned up.And you get the original ram rod. The rest of the "gun" will be from the new kit and parts that come with the stock. IMA says that the locks came from England and were made there, but when they were give to the Kingdom, the Nepalese did not want the EIC logo on it because of the cross, and filed it off, destroying all English markings off the locks, who knows if this is true or not or if these were made in country. The bore on my musket is .78 and I do shoot it, I honed it carefully when I first got it after soaking the whole thing in Evaporust for a few days, it came out very good. It shoots good, but I would not pay the price for the 1771 marked musket, I personally considered it myself but decided against it, it was just too much money to spend. Hope this explains it a little for you.
