I have the scans from the usual suspects, ie JimZ and some other sites but none have a scale reference. The SVG file I have created using InkScape from those sources is less than desirable quality, mainly due to the original scans being of older or of less than high quality.
I'd love to see a scan of the original fins in matrix (or out), along with a ruler (1/16" measurements or better). JimZ site's drawings aren't of any use to me. Semroc's fins may not match the originals as well, and if they do, I'd love to see some originals to verify them for myself.
