Mea culpa, nothing to do with Italy, see above. I'm going to have a glass of Taylor's Port and lie down....If I can find the Bottle in my new kitchen, they finished remodelling it Friday.
I suspect the book they were referring to was indeed Forton's, probably an older edition, in Spanish.
I'm gonna stop digging anyway before the hole gets too deep to claw my way back out.

One more spade full: It was indeed Fortan's book he was referring to.
My navaja guy contacted his SPANISH expert who told him the Pictures in the Forton Navaja book are pretty, but the descriptive parts are better excised and used for toilet paper. He was a bit more descriptive, so i toned it down a bit.
