Does not seem to have the correct info for a dog tag, looks right, but wrong info. I thought it was BA County, but I can not find a BA County. Every dog tag I've ever seen has the word "dog" on it.
It's a tool tag, the company had the initials "B. A.", Co. stands for company. The number IDs the tool's spot in the case.
I assume the back is blank.
JMHO
Good job Washingtonian.
