Wakizashi in occupation period souvenir mounts? Advice needed pls.

[Atlantia]

Gentlemen,

Please take a look at this sword.
I've never seen anything quite like it, although the numerous applied Tokugawa mon are reminscent of mid 20thC tourist items (boxes and the like) that I've seen.
The hilt and scabbard are completely wrapped with silvered copper wire.
I've puzzled over how to get the balde out and discovered that the handle 'appears' to be one piece, and there looks like a ridge on the upper edge where the tangs outline is visible (poosibly). So I think it might be glued/fized into a slot cut from the top side then bound over the top with wire.
Which takes me to the blade. It looks to my inexpert eye to be a 'proper' Wakizashi blade not some piece of tourist junk.
In fact it looks relatively good and worth investigating to me.
Overall length from tsuba to tip is 457mm. Blade is 31mm x 5mm at start of edge.
So, do I potentially destroy the albeit crude mounts to investigate further?
Does the blade look good to you chaps?
Anyone seen mounts like this before?

Thanks in advance
Gene
