M70 Prewar Bull gun info?|What's New!|Forum|Winchester Collector

I am new to this forum. About 20 years ago when e-bay still sold real guns I purchased a M70 Bull Gun and have struggled to get it authenticated. Hopefully experts here can help. The rifle has s/n 14757, 1938 production? It has a 24" bull barrel with a straight taper measuring .780 at the muzzle. It is marked MODEL-70–30-06 SPFLD.- It has target bases at the muzzle, on the front receiver ring and the barrel centered 6" forward of the receiver. It has a Lyman 48 WJS receiver sight and a globe front with aperture insert. The action is a cloverleaf tang with the safety on top of the bolt shroud. The workmanship and finish on the action is simply exceptional as is the operation of the bolt and trigger. In horned mounts (sp) it has a Unertl target scope s/n 38587 with a 16x eyepiece. The stock is a full marksman style with a high straight comb and a full flat beavertail style forend, in a beautiful figured dark walnut not checkered, with a full checkered steel blue butt plate and a nickel finished forend insert and sling swivel with 7 threaded position holes for a hand stop. A fixed blued sling swivel inletted into the butt with 2 mounting screws. The overall condition is excellent ++ and appears to have had very little use. One of the scope base screws in the front receiver ring is broken off. There is 1 factory hole d/t in the rear ring. I have fired numerous bug hole groups with Fed Gold Medal 168 S at 100 yds. with ease and the 10 ring at 200 is not a problem with the Lyman. Any information on the history will be greatly appreciated.
