Good stuff, Kerryman. Thanks. Glad to know I wasn't losing my marbles concerning what D and F meant. GG's comment about the difficulty in telling the difference between the two strikes me as strange, however. I'm certainly no Greener expert, but the Facile Princeps I've seen have a receiver that looks totally different from the Greener A&D's. Maybe at some point Greener made Deeleys that looked like Facile Princeps, or vice versa.
