Brent,
Ovate (hint ovum) means egg shaped. The bottom half of the profile cross section is a hemisphere and the top half is like the small end of an egg with the top removed to form the rib.
The lever contour is the same as the four-barrel Martini project and nearly identical to the Hoffman.
I'm fairly sure that my Hoffman and G&H Martinis both had Model 8 BSA peeps as there are nicks in the top of the grip area from the aperture hitting the wood when folded down. The last Model 12 Martini that I got had one of the Parker Hales and they are clubby and not attractive. The BSA and the Parker Hales for Martinis are, I believe, inferior to the Lyman tang sights, the Parker Hale unsuitable for a high quality custom rifle.
