BBPhil, a friend of a friend... "you like that kid's bike, eh?" (looking a my DT) "Yeah." "You know who has one exactly like that he wants to sell..." So.... it wasn't a DT, it was a steel Swift. Sort of like lightening striking you, I guess, or your petition of certiorari to the Supreme Court being accepted.

My experience with info@swiftfolder.com:

First email asking to buy a Swift with Schlumpf crank, sent 3 months ago. No reply.

Second email asking to buy a frame set, sent 2 weeks ago. UPDATED: Reply after 2 weeks.
