I concur with Rick the Librarian. You do indeed appear to have a British Remington. Most of these rifles were re-imported during the late 1950's and early 1960's by Interarms in Virginia. Your rifle exhibits the usual British export proof marks that are typical of these rifles that were exported from Britain. In addition, your rifle exhibits a Weedon inspection stamp, thereby indicating that your rifle may have been repaired at a British arsenal.
Hope this helps. Thanks for sharing!
