No disrespect to your photography skills Harvey but Ken is working off your images and they don't do the blade justice. Have a look at this site to see what can be done and good oshigata, http://www.aoijapan.com/
On the face of it you have just "another mumei wakizashi", of which there are many and most of little interest. Brian was pretty spot on with his assessment of the whole deal, non Japanese shirasaya, cobbled together mounts and so forth. And the nakago has been over cleaned. None the less I thought the blade had something going for it, hence my suggestion about an oshigata. Not sure where you are but if there is a sword club anywhere near then I recommend taking it along for someone else to have a look at in hand. I do happen to think that there is more to this sword than meets the eye from the images you have given.
Another idea is to see what a polisher thinks, please take advice on this as you really need a properly trained polisher. In any event if you are thinking of sending this to shinsa then a good polish and shirasaya would be a great start. For what it's worth I think someone who knows what they are seeing could give you great advice here, find a sword club.
