Finally got a chance to measure the barrel, this is the update post with detail pictures.
Make: Springfield Armory
Model: M1 Garand
Location (city or county): LA/OC/IE
Will ship (Y/N): N
Other info: WWII, serial number indicate Feb-March 1945, all parts are USGI SA, barrel is 1945 March, TE is 0.75, ME is 0.5, almost like a brand new barrel.
The stock is from a later date, just have not been able to find the correct time stock at a reasonable price.
It will be hard to find another Garand like this.
Will also comes with 3 clips of 30-06 Black Tip M2 (24 rounds), just in case you want to penetrate couple inches of steel.
