I gained valuable knowledge from this thread. I was never quite sure how the Rochester Defense Corp./National Postal Meter arrangement really shook out until now. If I now understand correctly, the contract was awarded to the RDC but the carbines were manufactured and dellivered by NPM, RDC no longer being in existence at the time of manufacture and delivery. Up until now I believed, apparently in error, that RDC was an active subsiduary of NPM and actually made the carbines delivered to the government.
