I wrote about Bill Peabody’s Rhody Flatwing pattern on currentseams seven years ago. Three years earlier, I’d posted the pattern on a public forum. It’s funny how these things play out, because someone recently followed up on that old forum post with a Rhody Flatwing timeline that didn’t make sense. I don’t know when Bill Peabody created the pattern, but it had to be some time after 1980. Before his death, Peabody clearly stated that Ken Abrames’ flatwings were the inspiration for the Rhody. I’ve also had conversations with Ken where he talked about sharing some of his flatwings with Bill. The point is: Ken didn’t start experimenting with the modern saltwater flatwing until the late 1970s, and he did not share them with the Rhode Island fishing community until the early 1980s. So. The Rhody Flatwing had to have come after that.
Here’s a link to the original Rhody Flatwing currentseams piece.
Below is a pdf link to an excellent article by Tom Keer from the Summer 2001 Fly Tier. Part of it is about Ken and how and when he developed the modern saltwater flatwing.
