https://www.facebook.com/permalink.php?story_fbid=1016771798689386&id=100010697251827 I saw this post on FB, of a warehouse of vintage BSA parts & bikes being sold off, they are stored on the South shore by Montreal.
From reading the seller's comments in French, she wants to sell the whole lot in one simple sale; she apparently has a full inventory in PDF format available for interested buyers if you contact her.
There has been a lot of local interest, so I Imagine it will move quickly, but she is willing to work with International buyers.
If you know anyone that may be interested please feel free to pass the info along, I get the impression it's probably an estate type sale.
I don't know the seller, so all the usual warnings apply.
