The "H" in shield sight people on this site and others are referring to is the type II milled version. The sight on your IBM is a type III stamped version. As stated some type II "H" in shield rear sights did appear in the 3.93 range (at least). If you could post one or maybe two more pictures of the rear sight from the top it should tell us if your sight is a replacement or not. When you take the picture(s) make sure the sight is adjusted all the way to the left so staking or index marks (possibly both) can be revealed.
