Belt plate thickness 1st Century AD

[Doc]

Does anyone know on average how thick belt plates were in the mid 1st Century AD specifically belt plates that had embossed decoration on the surface such as emperor/cornucopia and wolf/twins belt.

How thick were the above belt plates?

How were most of these types of embossed belt plates made? Were they punhed thin brass sheet wrapped around a thick brass plate that served as a backing or was the belt plate one piece punched out of a thick brass sheet.

I was under the impression that these embossed belt plates were about .5mm thick.

However, while I was speaking to certain people (out of respect I will not mention whom) it appears that .5mm is too thick for any embossed belt plate and that these types of plates (according to these people's opinion)were thin brass sheet wrapped around a brass backing plate.

Were embossed plates filled with pitch since they were thin brass sheet and then put on a backing?

Does anyone have a photo of the back of these embossed plates. Was the reverse flat or did it have the indents of the punch?

From what I read in B&C and other Roman books and then from what I hear from armorers, the story about the embossed belt plates gets muddled and keeps changing. I have no idea as to whom has a concrete idea
