Wilkinson British Military Sword

For the approaching Christmas season, I am hoping to acquire a blade for my father's collection. The only true criteria I have for this piece is that it be Wilkinson made, Military, and in fairly decent shape.

I've reached my wits' end trying to obtain one that fits my budget ($400USD) just as much as the picture in my mind of what I'd hoped to present to my dad.

After a couple bait and switch instances from antiques shops, and 'Sorry, it's sold' from online vendors- I've come here.
