Tricky viewing from my wee phone screen, but the rear brake hanger looks a little like an early Marin. Better pics (or in my case bigger screen) of the tell tale bits would help - rear dropouts, rear brake hanger, cable runs (if cables are run close together), fork dropouts, seat clamp etc usually are the tell tale marks between one brand and another.
The Reynolds sticker might be a 'ringer'; a quick look on eBay will show you all manner of sow's ears transformed into Tour de France winning marques all achieved by the cunning use of decals and stickers.
Thanks for that Radar
