These need to be re-certified, was quoted from a place of $2.55 each.
They have normal use surface scratches, but will stick to each other very good.
The only number on the box-case I can find is "13615"
The wooden box case is scuffed up on the bottom and has has other blemishes, the hinge and latches are in good working order.
Block size .051 has a blemish on the numbered side I don't know if that would need to be replaced but the majority of the surface is good.
It slays me to not have a certification for you, but these where my dads and he didn't abuse tools and would get after me if he seen me using any tool incorrectly.
I am pricing them high, my cousin looked at them and said they are good, and these are vintage I do not know the brand other than "made in Germany".You can find better deals for gauge blocks if that is what you need.
I could be open for an offer, ask if you like. Or ask a question about the set.
There will be NO refund, no matter what the reason.
Since I know the history of these and they haven't been used in at least 25 years,I can only guess the condition as, normal use, it is a used set.
I cleaned them off and rubbed the original stock grease on them from the grease that you see in the case.The grease cap looks like it was glued at one time and isn't showing up in the picture very well.
