Bike Forums - Vintage Locks

User [MENTION=81459]tcs[/MENTION] posted this photo in the Commuting forum of his Citadel lock and it made me look for a thread about locks. (Not a locked thread or threadlock.)

Sure, it could be picked, cut or jacked, but why bother when there are as nice or nicer bikes locked up nearby, secured with cables?

Anyone have any other locks? Anything pre-boom? Anything clever or weird from the boom? In my 1980's childhood we had simple chain locks with combination tumblers, or just hardware store chains and padlocks.
