It turns out this might be a Herrick design.

Focke Rochen  Fan

Design begins during 1944, it called the Rochen ('ray', as in the aquatic animal). A wooden wind tunnel model was built and tested in the mid-1950s with a simulated propulsion system installed. Focke filed a patent for the design in September 1957.

A might have been...Platt and LePage proposed extensive modifications to the FA-224 design, before abandoning the project to pursue what would become the Platt-LePage PL-3/XR-1.

Amazing info, thanks Platt-LePage! Did this project get any of the PL-1 or PL-2 designations?

There was no designation in Dr. LePage's papers, once it became apparent that no deal with the German govt. was possible, they started the layout that would become the XR-1. (The PL-3 went through a number of changes as the design progressed into the Dorsey Bill competition)...One early PL-3 configuration can be seen in this image:

At some point there should be a thread for PL-LP I suppose.

 You bet there should! But who would be better qualified than you to handle it? wink

Your picture doesn't show on my computer (filtered by my company's firewall). It's always best to attach the pics, or better, do both (attached pic will be small, but at least it will always be visible).

- during the 1945,Focke-Achgelis worked on a heavy helicopter with an increased loading
capacity
