Hi, I am new to Japanese sword, need your help identifying this Katana I recently bought: Katana in shirasaya. Signed: "Kagemitsu." Nagasa: 64.7 cm. Sori: 1.9 cm. Moto-haba: 2.7 cm. Saki-haba: 1.8 cm. Moto-gasane: 0.6 cm. Saki-gasane: 0.4 cm Do you think this is made by the famous 長船（おさふね）景光? Thanks for any opinions or comments!
