Overseas Charter Number?

[jb3]

I am in the process of having some new guidons made to replace ours that are older than all of our cadets. CAPR 900-2 covers guidons but my question is about the charter number for overseas squadrons. Ours was OS-100 at some point but also is listed as NHQ-100 since there really is not overseas "wing". In fact overseas squadron commanders fill the role of wing commander. I don't want to pay good money for flags with the wrong letters. Does anybody have some regulatory guidance on this? I'm not looking for opinion or even historic examples  as neither are factual enough. The reason I say this is because a good amount of squadrons in the US have guidons that don't follow the regulation so obviously enough of us are not experts. Thanks in advance for the help.

As listed in the current directory, it's NHQ-[charter number]. My olde unit started out as 99113, then became OS-113, and is now NHQ-113.
