Alah 1977 Raleigh 753 Team bike, on the small "lightening" holes. Lots of bike stuff on Ebay comes from garages and attics form years ago. This looks like a project that never got finished. Dickey Greer West Monroe,La USA
You can easily see where the track ends were cut away and plates brazed in
to make "vertical" dropouts. Not sure what the holes are for, unless they
were intended to mount a reinforcing plate.
