I have a Springfield, as yet not identified by maker, that has an unmarked bolt peep. After much searching in the "Old Sight Book" and Michael's books, I finally found one. It is in Part 3 of Mister Rifleman, where Colonel Whelen's guns are pictured and described. It would be about page 310 if the Part 3 pages were numbered. The title of the page is ".30-06 Springfield Hunting Rifle". The sight was installed at Griffin and Howe. The sight is described as "a Lyman peep of their own design on the cocking piece, having both windage and elevation adjustment". The Whelen gun was stocked by Linden. Have any of you seen this sight before? Do any of you know what it is and where it came from? I'm a little light on early Griffin and Howe catalogs and find it strange that Stroebel did not mention it in his book.
