Hi Ted- AB 460's are tuffer than most people think...
I used to own this Jennings example, it sold recently on eBay. Seems like it went for a steal.

Not suggesting this is scarcer than the Doyle (although it might be), but here's my Wheat AB 460.
PS- This Hoblitzel Blank Back is the only known example.
