Double-check the spelling of the author of your books. I think they were written by L. R. "Bob" Wallack, a different guy than Lester Womack.
Wallack's American Rifle Design and Performance was published by Winchester Press in 1977, and has an ISBN of 0876911947.
Wallack's Encyclopedia of American Gun Design and Performance was also published by Winchester, with a second edition appearing in 1987. These Wallack books are also available on Amazon, and sell for about a tenth of Womack's book.
As you note, Wallack was both an author and a gunsmith; he worked a lot with early benchrest rifles. Wallack lived in NY state; I think within the last year an article appeared in Precision Shooting magazine, describing a trip a couple of rifle loonies made to find his house and old shop. Wallack's first book from 1951, Modern Accuracy is a wonderful look at riflemen at the start of organized bench rest shooting.
