I'm excited too, bouldersmith. Nice rifle and I'm sure it will be fine. How's the bore? Since it has a wedge and patent breech, it will be easily cleaned. Can't tell about the original nipple (they called them tubes), but a replacement should be thought about. Trackofthewolf dot com might even have the proper threaded nipple in stock. YOu will have to measure the pitch and find if it is a whitworth thread, standard or even metric. You may have to make one. If so, pls get a standard 1/4/28 threaded nipple from a BP shooter or track, and copy the external in internal design. You do not want to damage the cock.
