Binky
I know you know bikes (and that you have sold a few), so I am hesitant to offer my two thoughts.
FWIW, this year at the Canadian Vintage Bike Show there were a lot of bikes of this type that simply sat and were passed over. I saw some amazing 60/70s bikes listed sub $300 Canadian. I posted a photo of a really, really nice Raleigh International listed for $250 that sat. I did forward the sellers contact information to someone on here. I regret not buying it myself.
Is this bike a foreign (non-Canadian model)? If it is perhaps this one might do better on eBay?
If you do sell it, please post what you sold it for. Might be helpful to have a number for the future.
Ps. If that Mancini for sale on Pinkbike is yours, it's a fine looking example!
Yes... Campagnolo, Gipiemme, Nisi and all..
