My girlfriend is pretty smart, for example from the return addresses she now knows and recognises Lynn's, Classicshaving, or one with an italian postmark (Maesro Livi), then it's bad news for me.

However some things can be sneaked under the radar, for example a 7/8 ATS34/Olivewood Maestro Livi looks quite a lot like a 7/8 Takeda-Damascus/Olivewood from a distance.

So upgrades you can often get away with - especially if you sell the one you upgraded from.
