Hooray, I got it out !!!
After soaking it in Kroil for about 2 days, I still could not get it out by just putting a socket wrench up thru the receiver and then putting the gun down on the floor to try to hold it while attempting to turn the plug.
So, made a trip over to my brother-in-laws house and after wrapping the barrel so it would not get scratched, placed the barrel in his vise by attaching vise jaws to the little extension on the bottom of the receiver that holds the stock to the receiver/barrel and then ran my ratchet wrench and extension up to an 11mm socket that I had on the breech plug nut and gave the ratchet handle a push and it turned almost right away.
When I got the barrel back home and looked at the plug after I removed it from the receiver, it actually did not look all that bad or at least not as bad as I had been expecting.
I think it is going to clean up real nice. I think the Kroil really did help because it looked like it had penetrated about 3/4 of the way down the threads of the plug towards the barrel end of the gun.
So, there does seem to be some value in 1) Kroil, 2) Brother-in-laws, 3) Vises.
Thanks for all your suggestions.
