Drawings and/or pictures of first century buckles

[Latinitas]

Does somebody know where I can find drawings or pictures of first century infantry belt buckles like the examples in the attached document? This could be websites, titles, scans, pdf documents, pictures of museum artifacts, articles etc. The language (when relevant) doesn`t matter for me since I am only interested in the drawings or pictures of the buckles and their dimensions (when known).

I already have the following books:
- Ad Arma
- Armed Batavians
- Katalog der militaria aus Vindonissa
- Gered uit de grond
- Roman buckles & military fittings
- The Pre-Flavian Military Belt: the Evidence from Britain

and the following websites:
- Roma victrix
- Dutch catalogue of "Het rijksmuseum van oudheden" where some interesting buckles can be found
- M C Bishop
- Romancoins

but I hope to find more .
