If that mike is still a current model it's an option worth considering. ..... They came back in as new condition for about half the price of a new set. So if they still have repair parts for that mike it could still be cheaper than buying a new one. An email about replacing the only two parts that could be worn as well as what series of mike it is should get you a fairly accurate price. Recalibration would also check and verify the anvils flatness so that could rule out a repair as being non cost effective.
I don't know if that mic is current. I don't have it with me, but I believe it was Mitutoyo made in Brazil about 40 years old. Several of the ones I have are made in Brazil. It just kind of bothered me because I have been doing a lot of bearing fits with it. I priced a new one and I am not going to spend that kind of money for a new micrometer at this time in my life. I ordered a new imported one just about an hour ago. I am thinking that I need a set of gauge blocks to check all my micrometers. The company doesn't have a set of gauge blocks. Which is really kind of odd with the new CNC mills and lathes they have bought.

As people have said, if the error is a constant, it's just a matter of adjusting the barrel until it is correct.
Testing with gauge blocks that are, for example, in increments of 0.100" won't tell you much because you are at the same rotation of the spindle.
Also, if your anvil faces aren't parallel to each other, you can get seemingly random errors when measuring round stuff.
