Lorica Squamata Literature?

[John W Davison]

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

It's not specifically Roman in coverage (the author is I think mostly known as an expert in the Byzantine army).  It's a short book (main text about 100 pages) and in spite of the name, the book really focuses on Iron age to early middle ages (e.g. Scythians to Vikings-sort of range).  Although the title says "in the West", it also mentions Iranian and Muslim use - I think "West" in the title is simply intended to exclude China/other Eastern Asia.  Amazon preview pages are quite extensive of you want to take a look:

Apparently he also produced a booklet (22 pages) on Roman lamellar bu I cannot see it on Amazon or the Book Depositary:
