Working on it; best guess for year range is '60s to mid '70s given lack of braze-ons and brake caliper mounts having exposed nuts, maybe early '80s at the latest. Lugs could have been cut out from blanks, or modification of an existing design. Does the rear derailleur say "PATENT 77 or 71"? I cannot read it. That year, if original part, will generally be within a 2 year time frame as to the actual year of the bike. Most common is to find the derailleur date one year older than the frame.
