Frankly, I can't tell if those are Model 70's or not, much less the time frame. I do know about the oddball scopes that were acquired, and I have seen some of them, but I have never heard anything about any of the Unertl sniper rifles being built at Albany (I was stationed there in 1970). That doesn't mean it didn't happen. As I said, I am no expert in the area of Vietnam sniper rifles, although I have friends who are. I think Senich and his works were a lasting great endeavor (as is Martin Peglar's books), I don't know anything about Miller, I neither know nor am I much impressed by the Chandlers (compared to Senich/Peglar), but Jim Land is a personal friend of mine of whom I think very highly. You (and the original post) have aroused my curiousity about the whole issue, and maybe I will learn something from the exchange.
