exactly like that except my rib is lower and the first vent is - what seems to me - inordinately far back, 2" at least, maybe nearer 3. I had lippard's book when I had my first perazzi. it was good in that it's all there is but it was woefully short of what a good book should have been. I doubt any will ever get written, like you said. I did have a book on Italian engraving, scarce book, can't recall the name, "something incisione something" I think. great pictures but not much in the way of history.

I rarely shoot anymore and then it's either garands, or sidearms useful with a chl.

thanks
