500 single crankshaft gear spring wanted

I know its along shot but does anyone have the fat spring (52mm dia.) that fits behind crankshaft gear on a 500 single? (I think they are all the same whatever year) I have sent an order to Guzzi Retro but no reply. could still be on summer holiday!

holiday? italy? august? traditionally, as I understand it, August is “shutdown”

I was being polite​:joy:
