MP liner that i have posted on here was gift from a very good mate. dated 68. i also have found that the unit was in vietnam in the 60s. i also have found a image of mr wright of the 615th but no wearing this liner, could just be a coincident. as i have found that a lot of these liners have been faked over the years. i would just like to ask if you guys think that this liner ticks all the boxs. im just about shore my self that the liner is right. it did come with a front seam swivel bale helmet . the shell has a smoth paint finish no cork or sand. thanks mark.
