Thank you for the links to the information on Murata-to. Mine is identical to that given to Prince Chichibu for practice. No signature, date or any marks along the top of the tang. I must have missed the 2016 thread and really enjoyed the comments and info.

Here are some shots of my Murata-to. All the fittings are copper and the saya is canvas wrapped. It is not sharpened which makes sense if it is a practice sword. Also there are no Menuki but ovals of wood to orient the hands on the Tsuka. No. 103 w/ arsenal stamp. Two mekugi ana . Amazingly it's in perfect condition,
