Have had this Irwin bit display for some time. This week began sorting through boxes and bags of bits that have come my way. The holder came with 2 rusty bits, wanted to see if there was enough to fill it. In 2 hours of digging, was minus the 9/16 and 15/16 . Then remembered a canvas tool roll I stashed away. Found 5 more pristine Irwins, which I swapped out the rusty stuff. All matching bits now save for a real common size in the middle. Not researched the age, but the prices make me think early 60s. Any ideas as to age, or any more out there?
