Oh man, you are 100% correct, it's a 5mmH7, not 7mm!
I'm going to have to buy a 5mm reamer ASAP, unless I find one locally. I'll make some calls because as you say I've got a lot of friends here with shops.
As for that load of pins, they're all gone. They were all imperial sizes, over 700 of them in Class XX. I had no place to store them at the time so I traded for a smaller pile of tooling I could actually use and store, from a dealer in Vermont. My goal is to (eventually) get a 3-set collection of Class ZZ 2" long pins in cases, from .011" to .500". The sets here run .011" to .060", another from .061" to .250", and .251" to .500". I'm resisting getting the Chinese made ones in favor of American made Starrett, Meyer, Deltronic or similar.
EDIT: What I think I can do is just drill it out with a 3/16" (0.1875") drill, then "ream" with a No.9 (0.1960") drill. That should have it come out right within the 5,0H7 tolerance. If you have a 5mm reamer, Darren, I'll just leave it for you to ream at assembly.
