Retro find: NES (EU+US)

Doing my sunday morning market shopping at my local town, i stumbled upon this really mint looking NES packaging including two extra games (Ikari Warriors & Bionic Commando). I wasn't expecting much on a reasonable price since the whole kit was in such a great condition, but out of curiosity i asked anyway.
The seller asked 5 euro, couldn't find the money fast enough! This Nintendo Entertainment System is originally a EU-PAL system, but it has a switch fitted to also accept and play US-NTSC cartridges. It's the 'Action Set' which includes the light gun and probably the most known double game cartridge on the system with the original 'Super Mario Bros' and 'Duck Hunt' on them.
What i also love about it, is that the original price tag is still attached, back then ofcourse in old 5.995 BEF, which is about 150 euro in todays money.
