The problem with items that are restricted or banned by definition (as opposed to, say, violations of copyright and trademark that are easily researched and dealt with), like this one, is that that there may be multiple versions of what the restrictions mean — what fits the description of what's banned?
The answer may well depend on who's interpreting the guidelines. The seller may have an expert intrepretation of the guidelines, but it's ultimately up to whomever is reviewing the listing, and that person may have another interpretation. It may be a dumb, ill-informed interpretation — I doubt that eBay keeps a staff of experts on call to examine possible violations in every single category and sub-category — but that's what eBay is going to go with. Or if 'bots are doing the review, it's up to whoever programmed the 'bot.
Frankly, for a lot of military antique items, a specialist website or a private auction would probably be a better venue than eBay — certainly, a friendlier one. eBay focuses too much on mass-market items these days, it just doesn't have the mental bandwidth to be accommodating to specialists anymore.
