It seems you have gotten the Chained Revolution info, but if not let me know. Also, maybe you'd consider adding a field for serial number location, as it was quite variable in the 1940s and 1950s. And you might consider adding a field for Original Paint or Restored? I know a Registry is different than a database...I do have a spreadsheet of a few hundred Paramounts from eBay ads, online sources, etc....often backed up with photos. If that would be of use to you, I can provide the spreadsheet....spreadsheet includes serial number location; dropouts; seat stay caps.
