Combination Set Lockbolt

[Nicholas Lingg]

Hi: This is my first time posting on this Forum. That being said I worked in the machinist trade for 34 years and have a home shop. What I need help with is: I found this 6" center head that is missing the lockbolt. It is .225" in diameter which is not a standard size for Starrett. Does anyone recognize this hear?
