Scooper says: "The OEM freewheel for the 1972 P15-9 touring Paramount was a Regina "Oro" with 14, 16, 19, 25, and 31 T cogs. They show up from time to time on eBay."

Thanks, nice that you can share a scan of the original catalog. I have the same cogs, how do you know it is a Regina? Neither the Schwinn catalog nor Bob Hufford's data book name the freewheel brand.

Yes, some are listed on ePay, unfortunately with the wrong combination of cogs...

Are they real gold/gold-plated?
