Apparently the museum would be called the 'MG MUSEUM', and would be supported by the local Lecco regional council who sees the Guzzi factory and museum at Mandello as a vital part of the local tourist trade. It'll all cost about 8 million euro though - so in these times of financial rack and ruin, it's doubtful it'll happen very quickly.
I first went to the museum in 1992, and I was the only person there. I had called beforehand and was told to be there at 3pm, which I was. A little old man unlocked the door, and ushered me in, and said I had 15 minutes! It was all in one room in those days, and the floor had an aged but fantastically period 1950s green linoleum covering. The bikes on display were unloved and not looked after, covered in dust and cobwebs. There was no 750 S3, and I asked why. "Don't know came the reply." Some bikes had bits missing, or different sidepanels. Anway, an experience, and how the museum has changed nowadays.
Here are some shots of mine from that very visit. The Motozappa was my favourite exhibit, and I regret not buying one cheaply a few years ago when I lived in Italy.
