Hanging straps on balteus?

I am curious to know where they got the idea that apron studs were domed - they are not. All of the Museum of London ones (yes, I've seen 'em all, so am officially 'sad'...) are flat-headed.

As we see similarities with belt plates (Colchester/ Vindonissa) some studs could be from a particular fabrica, hence the London finds are flat.

I have seen photos of a supposed single 'apron strap' (desperately looking for a photo noew) that has overly domed studs? Or would you say that it is probably a horsegear fitting? There are also some other domed stud examples in your Military Apron article.

If the backing rivet is peened on a soft surface such as wood, you do get a degree of doming occurring centrally on the disc.
