Stumbled across these old films of Glasgow on this site
http://www.clydewaterfront.com/heritage.aspx
I'm sure some of them or parts of them have been posted on here before, but they are worth another look.
* Glasgow 1980 (1971)
* Glasgow Docklands (1956)
* Queen Mary (1957)
* Seawards the Great Ships (1960)
* River Clyde (1939)
Lots of good shots of the broomielaw, kingston bridge construction, shipyards , Erskine, Finnieston and Renfew ferries (and Renfrew boat yard).
