This toggle-locking rifle chambered for the .30-06 cartridge is the second of two rifles submitted by White for the 1930 US military trials. It was not actually tested by the US, but White did take it to the UK where it was tested in the early 1930s. British officials liked that it was a positively locked action (unlike Pedersen's toggle rifle, which was delayed blowback), but found it too fragile for combat use.
