Hiya Giorgio, I'm confused, which bit are you 'restoring'? More than likely, my uncouth eye is blind and the other one's no better, it looks just friggin' fine to me!!! The rear mudguard bracket(maybe just camera angle), and the engine pipes, seem fabricated, but geezas-beezas??
The bar just went up, enough for me to do chin-ups !!
Cheers, duTch (mine's a kindof '52 also, but looks nothing like that, )
