This is a authentic experimental Mitchell pattern custom made officers uniform shirt. This would be a slight but actually before Korea. They Mitchell pattern was developed and in experimental use long before it was actually accepted by the USMC.
You can google all that information. The ww2 uniform that I own with actual names or name tape are actually over the left Brest pocket so it would be before the military made the branch name plate over your left Brest.
This shirt has been to the show of shows more than once and one concurrent fact between everyone. They have never seen one like this or it's pattern. Either in a real uniform or a reproduction uniform ever. And one of the for most military uniform authentication experts actually said that there is writings of an actual ERDL Mitchell pattern uniform that was experminted with but there are no known pictures and he actually believed this is one.Feel free to ask any questions.
