6. I've never heard or the Wentworth valve, but I am familiar with the Dunlap valve

and it would have been totally appropriate and readily available for the Swiss Army bicycle: The Dunlap valve was more robust then the Presta and the threaded stem was more secure then the Schrader valve when filling; perfect for ham-fisted Army dudes

The big improvement in the Dunlap valve was when they replaced the stupid rubber tube valve thingy with an engineered valve insert similar to the Schrader valve.
