I seem to recall that John's sister and her husband set up one of the Dundas St. buildings as a high-end bicycle shop adjacent to the McBride motorcycle shop in the old bowling alley premises. This arrangement did not - as far as I heard - prosper sufficiently to satisfy all parties involved and so the business was wound up and closed down. John then set up Rider's Choice as a separate business.
Remaining British motorcycle stuff went to British Cycle Supply in Wolfville, NS and they still advertise on-line the occasional "finds" of NOS Royal Enfield, BSA and even Ariel parts from the McBride cleanout as well as new and recently produced parts for British bikes. The other source for British motorcycle parts is Walridge Motors Ltd., north of London, ON.
