Levi’s lvc sawtooth denim shirt 1955 authenticit

Hello,
I bought a levi’s sawtooth shirt 1955 ,
pretending that is lvc, made in USA.
I have another one made in 2014 and there are some differences.
1. The tag showing the size “M” is not attached to the bottom of the square tag in the middle bellow the collar but separate in the left side attached to the collar stitch
2. On the right side of that square label attached to the collar stitch is a tag
please read here

3.There is no any sigh that originally were any labels attached on the the left inside stitching/the four tags with all information/
4 . The square label in the middle bellow the collar is stitched with white thread instead of yellow one.

Generally the shirt looks good and the denim is tick dark indigo.

Any opinion if that is a legit one or a good replica.
Thanks!
