I had an opportunity to bid on a Type 38 Arisaka the other day. However, it was marked on top with ".256 SPENCE" I went to the net and searched, and could find nothing but a reference that stated "Many Arisakas were rechambered after the war for .256 Spence." I could find nothing on the .256 Spence, and I had to forgo the bid. Anybody got any idea what this wildcat consisted of? What cartridge it was created from? This one really bugged me, because it's so obscure. It was a really nice Type 38 sporterized version, too, but apparently became a "closet queen" because the ammunition was unavailable.
