Vintage 1970’s 80’s Blue Box Tool Center

Not sure exactly what year this is from, but considering it was made in Hong Kong it’s from the late 70s or early 80s. The only tool that is original to the set is the wrench, it’s the only one that is marked Blue Box, made in Hong Kong. The rest of the tools are older, however, they were made in China. I believe the bolts and the screw were original to the set. Overall, it’s in good use condition for age.
