Here's Remington_521T_JS_prelim.pdf, just a little doodling this afternoon for a few hours. Only some flood filling, straightening and text repair [and some square brush work]. The component parts page is where the big work will be. Definitely needs at least 5 more hours of serious work.
I sent you an email with the pages as PNG graphic*files, which might help you edit.
