3 jaw top jaws

Center cutting end mill :oops:, but I need a new one now:(
 
Well the work is done, the jaws mounted fine, but the internal jaws do not have the same profile. There is now a gap if I seat stock all the way in the chuck. I'm thinking I'll need to check with Pratt with the serial number, and get the right jaws. Oh well...
 
I'll have to check with Pratt America, this is a PB International.
