Jim,
You will be delighted with the service grade.
My first service grade showed up two days ago. The wait was 55 days with the holidays during that period of time. I've purchased a number of correct grades and one collector.
I was shocked how nice the service grade is. I still haven't dismantled, or cleaned it, there was more cosmoline on it than the other rifles. I do know the bolt, reciever, barrel and trigger assembly are all Springfield Armory. Muzzle Erosion guaged out at just under 2 and the throat erosion was right around 2.5. Parkerizing overall was around 90% and the walnut stock and handguards were in surprisingly good shape, better than a couple of the correct grades I've purchased.
Something doesn't look right about a Garand with new furniture. I put new Wenig Bastone Walnut on a Garand I had DGR completely rebuild, rechamber to 7.62 and reparkerize it really was a beater. The wood literally knocks your socks off...but something about new wood on a Garand...it's just WRONG!
Order the service grade, it's worth the wait and you'll be glad you did.
