Yes, stock looks great! Love the nice rollmark especially on the early ones. Grooved clip and very nice HGs!

barrel swage during rebuild
While not rare to find but not something you see everyday is the roller marks on the outside of the barrel. This barrel was swaged in order to index on the receiver

Springfield called it "rolled" and sent many barreled receivers to repair for rolling to correct "light draw." I take this to mean the barrel didn't mate to the receiver correctly because the shoulder was a few thousandths short. Swageing squeezed it a bit longer. This was evidently done in the Model Room. On May 6, 1938 a group of 19 from 1060 to 2394 were sent and three days later 7 were sent back for more squeezing.
Real men measure once and cut.

That looks very heavy swaging to me. Was this done with the receiver attached? Does not seem it would take that much to move the metal a couple of thousandths

Mark, the swaging is always done before barrel installation. If you screw the barrel into a receiver by hand it should stop about 3/16 inch (approx)
before index. You then tighten the barrel with the wrench. Sometimes you screw the barrel into the receiver by hand and the barrel will go past the index
and then you need swaging to expand the area above the threads for the correct index.
Others (myself included) have used a hammer to gently tap all the way around the rear of the barrel to provide swaging and works most of the time - but
swaging in a lathe with rollers is still the best.
The big debate years ago was did Springfield use swaging on new production receivers and barrels during WW2

I have also tapped the edge to correct the draw - that just looked heavy to me
