M1 Garand Tanker barrel and op rod kit .30-06 Springfield

Rare M1 Garand Tanker kit in .30-06 Springfield caliber that includes barrel, op rod, follower rod and spring.  This kit has been purchase about 20 years ago and comes from a working rifle.  I always wanted to built it but never had time, so here it is.  It has vintage marking on the barrel, bore is mirror bright.  Op rod has a perfect piston and tab.  This need to be mounted by a gunsmith to have the proper headspace. and need proper fitting.
