Thanks to some APR Patreon crowdfunders, I was able to procure a *giant* blueprint of the Grumman F7F Tigercat from ebay. Today I got it back from the print shop where it was scanned at 300 dpi, resulting in an image more than 29,000 pixels wide. The image was processed a little bit to reduce the file size from 900+ megabytes down to 100, and a half-size version and a B&W version. These files have been provided to the funders. The blueprint itself will now be sent on to a relevant and worthy museum or archive.
