It is a British Pattern 1907 bayonet, but it has been rebuilt, maybe more than once. The scale screws are reversed; the slot heads should be on the right.
It may have been made in England, or about anywhere else where the rifles were made (India, Pakistan, Australia) and could have seen use about anywhere in the British Empire. As the old saying goes, "if it could talk", but without speech it is not worth much in dollar terms.
(Edited to change "M1907" to "Pattern 1907". I do know better, but it was late at night.)
