Well, they are called "kits" but they come as a box of raw castings, a unbreeched barrel without dovetails for sights or underlugs to attach the stock. The only things that actually are close to being finished is the lock and set triggers and even those need work to attach them to the stock and to remove the rough cast finish. The stock is just a roughly shaped piece of curly maple with the barrel channel cut (but not finished).
Each one of them took over 150 hours of work to finish.
