Navy Luger

[rpbcps]

As Tom Armstrong said in his sticky 'Navy Luger Inspections',
"Because of their great rarity and sky high prices, 1903 Navy prototypes and 1904 Navies fall into an entirely separate category and anyone contemplating such an acquisition should exercise all of the caution and due diligence requisite for a purchase that equates in cost to a luxury automobile".
Even here in the UK, a deactivated Navy Luger, the only way we can own one, due to our draconian gun laws, costs a kings fortune, but I'd love to add one to my collection.
I noticed one recently on the web, but due to past experience, I am always very cautious, so I thought I'd pass this by your expertise in the subject, for your opinions, real or fake?
Photos below.

The cross swords in the UK deactivation mark and the letters EU/GB etc. on the left hand side of the trigger frame above the pistol grip are the European Union deactivation mark, loads of letters....
Thanks
