I'm not sure about the type of feathers, but they are not turkey feathers. There are three feathers on each, but one has two feathers missing, and another has one feather missing. Four have three feathers, but they are used, so there are some missing feathers and scuffs. Please refer to the images for the condition. The shaft is marked with "1913". The nock appears to be a square nock. Sport: Kyudo (Japanese Archery)
