I bought this set for $8.00 at auction about six months ago not knowing it was metric until a few days ago. Note that the box does not have any writing on it (did it ever and was paper or other somehow wiped off)? When the biding was so low I bought it to resell. Few days ago I looked at it to see if it had a 1/2 20 in it and found out it was metric throughout. It is all there and I'm wondering the age. I'm beginning to think I may have too many tools????? No, it is no longer for sale.
