Hello there, I need help with the authentication of a sword I recently purchased, it is supposedly from the Muromachi period and signed by a Norimitsu. It was valued at €700-1000 which i would also like to know if thats accurate (i assume it was vastly overpriced in the valuation) but would mostly like to know if it is indeed from the Muromachi period and if the signature is genuine/any details are known on what Norimitsu. I also do not speak Japanese so cannot read the registration card.
