IMHO this is indeed an older rifle sent to Suhl for rebarreling.
Often GIs did not know that German guns sometimes had two or more interchangeable barrels. Take f.i. my family heirloom Meffert Hubertus gun. It's original damascus barrels were smashed in 1945 and the stock broken. But my Grandfather had two pairs of new barrels made and Nitro-proofed at Zella-Mehlis in 1942, 16 & 16/70 shotgun and 6.5x52R aka.25-35 &16/70 Buechsflinten ones. I am the fifth generation since 1893 to use it.
By coincidence one of the few true H.Goering rifles surfaced just a few hours ago: It is also a 7x75R vHSE, already well documented from the making in Suhl end. This one apparently solves the mystery of the "Epl; Stuttgart" who ordered the first batch of cartridges from DWM. The Goering rifle was ordered to be made by Edgar Strempel, Suhl through Robert Eblen, a gunmaker/dealer at Lange Str., Stuttgart to be presented to H.Goering by a Mr.Truchsess.
