Part No 4646574

I was doubtful when Luca asked for my assistance in finding Lego part No 4646574 (vehicle roof) and I eventually had to give up.
Luca however persevered and found it, for a bargain price of 60p :-)

Unexpected day at home today waiting in for a Scottish Power engineer to fix the leaking boiler - to them, a 'morning appointment' doesn't actually mean a 'morning appointment' in the traditional meaning of the words...
Anyway, as expected, it needs a part, and a return visit.
