At
The Education Forum today, when talking about Elmer Todd's initials being located on CE399, Vince Palamara said:
"That "E" and "T" look mighty big (and awkward) to have been missed by ANYONE all these years. A clumsy, awkward late addition?"I think Vince needs to take into consideration the fact that the photograph that contains the "ET" marking on CE399 is a picture of the bullet that has been zoomed-in and enlarged considerably in order to highlight the "ET" area being focused on.
In order to put the actual size of the bullet into better perspective, here's a montage photo I created that shows on the left side a human hand holding Commission Exhibit 399 and on the right is the new hi-def photo of the nose end of the bullet with Elmer Todd's initials:

I think it's clear when looking at the "bullet in the hand" photo on the left that those "ET" initials occupy a very very small amount of space at the nose end of that bullet.
The full length of a Mannlicher-Carcano bullet like CE399 is only about 1.2 inches (per the Warren Commission testimony of FBI firearms examiner Robert A. Frazier). So the actual size of Elmer Todd's "ET" mark on the bullet must surely be measured in mere millimeters.
So perspective plays a huge role in explaining why Todd's markings look so large to Vincent Palamara.
