Different materials, different thread counts in the embroidery, in some cases very poor detail in the insignia or poo fill-in.
I may have some remaining in ColganMart. I will have someone look for me (having difficulty moving heavy and large boxes due to medical stuff) ASAP.Since ColganMart prices are so good, I quickly sold out of most of my supply. Plus, I donated to some needy cadets.I also have to check with my neighbor to see if they're still willing to mail stuff out for me now that they're back. Give me a couple days.
We checked. I don't seem to have any more Lt Col epaulets. I do have a number of 2d Lt epaulets, as well as some ultramarine 2d Lt insignia and 2d Lt GoreTex parka tabs.
You'll need to add your information and get it submitted to your CC. Good luck. If you want, I'll write you a recommendation letter.
