GI Round Bolts

[INLAND44]

The thread about the 'D' bolts started me thinking about mine. I have two bolts that can be used in my Inland. Both are 'round' and have no gas relief port. One is 'AI' - I know what it is but can never think of how to spell it - 'Autyere' (or something) for Inland. The other is 'OI' with a sideways serif '2', all markings on small lug. Who is 'O' in this case? The 'OI' is original blue, 50%, and the 'AI' is a very dark but not black matte finish. Both bolts have been inspected, gauged and test-fired. The 'AI' is actually the spare bolt.

Hi, The "O" is for Overton. Take care. John

Its amazing that they made stocks as well as bolts.

Companies seemed to have made all manner of unrelated items, but I must say I'm sadly disappointed that my Rock-ola doesn't play any tunes

The O on the bolt isn't Overton nor is the A Autoyre. The marks are for Monarch Marking Systems and Dayton Racquet Company respectively.
