I'm not sure why a person can't find application charts online for these vintage sights, but I suspect that the rights to such have been sold and subject to copy right protections. I've searched many times and always come up empty, except... for "Cornell Publications LLC", they print and sell vintage catalogs on various gun related products among others. They have Redfield catalogs going back to 1938, whether they include application charts is another question. They aren't expensive but if they don't include the information you need.

Seems like nearly all searches for historic data always comes back to Cornell Publications.
