Need help identifying Wakazashi

Attached are 11 pictures outlining what I believe is a Wakazashi. I inherited this sword from a dear friend of mine and he knew everything about it and I even remember him talking about it on a few occasions. I thought he had paperwork with the blade but after his passing it would be impossible to get it. With that said, can anyone tell me anything about it? This was a close friend of mine and I know nothing about the sword which I feel is a disservice to him. I’d greatly appreciate the help.

I'm sorry for your loss.

My concern here is what happened to the kissaki. It looks as though someone took sandpaper or some object to it. Could you get a close up of it? The kissaki is the very tip of the blade.

For posterity's sake I've attached the photos here.

I'll chip in my thoughts about it. It's most certainly authentic. Please do NOT clean it in any way. That can damage the sword and it's value. Any polishing or cleaning should be done by a professional and not someone down the street who knows how to use a grinder. Does there appear to be any form of a mei (signature) on the tang? The wooden sheath and handle are shirasaya mountings, which are used to store the blade. The other is koshirae, which is the mountings it is in when it isn't being stored. I can't approximate the age sadly, but this is my 10 cents on it.
