Another guy to check with on these round dates is named Arthur Porwick. I think he worked on that project a bit. Hexter didn't stick around after the mess in Charleston PO.
Rubber/Plastic self-inking inserts were all the rage throughout industry at roughly that time (1980). Still are!
Your own exhibit of “validator or oblitor 570 shows a 4 digit yr stamp, and it is also shown in the engineering drawings I linked to. Is it not the closest to the postmark on Obamas SS registration? It is round not oval, it contains month day year and PO location.
Why you want to check us to check with people we dont know amazes me, you are making the claim not that they had 2 year date stamps or that there were individual digits not 4 digit inserts...you check if you know these people. Check with a window clerk supervisor from 1980 who stamped the SS registrations. I know the answer and you refuse to accept it. Prove me wrong, please.
Now please show me 2 round date stamps/postmarks that have only 2 digit year on them. No one else has come up with any but Obama’s. Also explain how the validator RDS could only stamp 2 digits (no baby powder please or do they deliver babies in the PO also?)
And you never answered if you wanted to accept my friendly chance to get $100 donated to FR, but you keep insisting anyone could have filled out Obies SS registration and it could have been at other than a post office. Wrong.
You just keep wiggling and squirming out of your WAG (wild a$$ guess). You claim you want Obie out of office more than anyone else, why do you keep posting disinformation that benefits him?
