Someplace, I have or had the complete optical parts list, focal lengths, glass types, radii, spacings, etc. for the Mk. 41
But I have not seen it for years . Has anyone seen it, in the estates of acquaintances RIP, to whom I may have lent that information? I could get another copy, a few decades ago, and yet my be able to do so. What would such documentation be worth?
As previously mentioned, I called a few weeks late, after B&L threw in the towel on US binocular production, in the mid/early 1970's. The body dies for Mk 41, and much else , were scrapped or went out the door. I was told " if you had called me a few weeks ago, I would have given the body dies (molds) to you at no charge. They were scrapped".
Robert E. Hopkins (RIP), Univ. of Rochester, see Mil Handbook 141, etc., told me at SPIE in the late '70's or early '80's, that he designed the eyepiece for the Mk. 41. His daughter was in a Spanish night school class which I attended.
Has anyone seen similar documentation re the Sard 6 x 42, which has somewhat better field correction, in my opinion, with 6 elements in the eyepiece, vs. 5 in the B&L Mk. 41.
