I’m afraid you’re right about their rider. I am going to call them tomorrow. I’m not necessarily after a 17th century sword, I’m just a casual collector. That being said, this experience does make me want to learn more about Nihonto and possibly becoming a more educated collector. It does make me wonder, however, how they could have been 300 years off. Seems fairly blatant. I will be interested to hear why they listed it as 17th century…
