My Father recently passed away and among many, many types of tools, I found a set of 29 drill bits (1/16 - 1/2 x 1/64) in an orange metal case with no markings of who manufactured them. Each drill bit has the size and the word AUSTRIA imprinted above it, that's all I can find. I'm pretty sure they're old (20+ yrs) as most of his tools were, although many were never used, as these look. (He was a bricklayer for 40+ years, but he just liked collecting tools apparently !)
If anyone is familiar with them and can tell me who made them and approximate cost, I'd greatly appreciate it, thank you.
