Bit of a thread resurrection...

Anyone know where to get these in something approaching a 15"-16" collar and without the USMC insignia? I've had a bit of a trawl but I'm struggling... Any help appreciated!
Thinking with minor modification it'd make a nice quick-n-dirty Gorman working dress shirt.
Looks like the P1958 USMC utility shirt I posted earlier in this thread. Could be the P1956 though which had an herringbone twill.
Might help you in your search knowing those numbers.
and they have a catalog so might sell them.
