Hi,
Many thanks for the information. It's pretty amazing what can be told from just you guys looking at a couple of pictures.
Just to clarify, though, the sword wasn't found 'lying about on a building site', I had said that my friend found it on a building site. Perhaps I should have been more specific; he found it in a loft of a building which was being torn down, minus its tsuka and tsuba, but with the saya present. The saya seems to be of the military type, metal with a wooden liner, the laqueur is a mid greeny-brown colour. There's a motif on the metal hanger at the top of the saya of a ten-petal flower on top of another larger ten-petal flower.
I'm at work at the moment, so I won't be able to get the pictures uploaded until tomorrow. I'll try to get them on in the morning.
Kind regards,
Francis.
