I, too, only remember the Woods & Presta valves - the latter "high pressure" valves on (5-speed) "racing" bikes in the early 1960s.

The first Schraeder valves I remember seeing were on the rear wheel of the Raleigh Chopper, which kids had to go to the local garage (UK-speak for a petrol/gas station) to pump them up using the "free air" line.

Woods & Presta valves are the same thread-size and, incidentally, this is usually the same thread-size as t'other end of the adaptor or hose - where it screws into the body of the pump.

However: a lot of Woods hoses wouldn't work with Presta valves as they snagged on the brass screw-up thingy at the end of the valve. A Presta hose had room for this, being "hollowed out" more - and, of course, worked for Woods valves as well.

I often file off the pointed end of one of the pump pegs on my Raleigh 3-speeds, etc., so that the Schraeder hose will fit on what was originally designed to fit a Woods hose!
