Could I please get some thoughts on the markings on this firing pin.

It came out of a 5.15 serial range Inland.  I thought that everything in it
seemed to be factory correct, but would like some help to confirm what is 
marked on this firing pin.

To my eye it's OBB. Other thoughts?

Thanks in advance.

Request for 10,000 FP's from IBM to Inland 11-25-43 WB!
Maybe one of those was in the parts bin?

Thank you for the quick responses. Much appreciated!

The carbine shows a barrel date of 6-44.  And as mentioned all the other
parts seem to show correct markings for this range of Inland.

Would the transfer date of those pins from IBM be way too early to for
one to have possibly made it into the bolt of this Inland carbine?

Maybe post some pictures for the more Inland knowledgeable folks than I. Anything is possible with carbines. It needed a firing pin; pull one from parts bin and assemble. Rule of thumb, don't correct it.
