Here's a few pics of boxed Runts. The 48 in the 2 pics for the most part date from the late 1940's to the early '50's.
The No Snag Runts were only made from 1941-1943. The box catalogs pictured are the only ones I have seen that actually have the No Snag in them.
I've recently done some research on box catalogs...and once finalized...I'll post up the info for you folks
