Lorica Squamata Literature?

[Sean Manning]

Are there any Empire/Region wide Studies, Surveys, extensive overviews etc, of this armour, specifically Roman Squamata ?

After you have read the big broad books like Robinson or Bishop and Coulston (or M.C. Bishop, "Body Armour," in Yann Le Bohec (ed.), The Encyclopedia of the Roman Army (Wiley-Blackwell 2015) vol. 1 pp. 1-8 http://mcbishop.co.uk/upload/body_armor.pdf), I would honestly recommend tracking down the books and articles in my overview of surviving scale armour. If you know the best preserved finds, you can interpret the sculptures and the fragments from other sites.

Edit: I flipped through a copy of Travis and Travis, Roman Body Armour (Amberley 2011) and the section on scale and lamellar armour looks OK
