heres another pic / sorry, didnt know that it had been posted and dont know how to delete it!
Quite a story with this blade, when purchased the showa stamp was actually hidden on the tang as it was filled in with colored wax or dirt of some type and I discovered it while oiling the blade as some of it dissolved in the choji oil! I then put a little lighter fluid on the area and -- the stamp appeared. The dealer in montreal was upset as he said he didnt see it before he bought it and sent me a tsuba, a sword rack and an antique print of a samauri in compensation.
The tsuba, koshi, and all the furnitire is signed as well so I dont think I got burned too badly but you can never tell!@
