The AK in medieval dress: no blueprint to learn, the plain AK's bill of 50 high quality metal, springs, wood and a rifle body. The skin adds nothing to it.
Themed rifles have a way of ending up in a box. Someone takes one off a raider, it looks too good to lose, and it sits next to the furnaces for the rest of the wipe. Read this page as a reminder of what is sitting there: the assault rifle's full bill, a rifle body included, the one part nobody crafts.
There is no Medieval blueprint to research. If you own the skin, you pick it when crafting a plain AK, for the same high quality metal and not a fragment more; nothing in the row sets it apart, recycler yield included.
A spare one belongs on your next roamer, with a stack of 5.56 rounds, not on a shelf.
