From 1782 to 1788, Christianus Fridericus Matthaei (1744-1811) published a critical text based (I'm told) on a collation of about 70 relatively late manuscripts. The Apocalypsis (Revelation) section was published in 1785.
His text of Revelation 16:5, naturally, does not include Beza's false correction to the text. What follows are Matthaei's main text, his apparatus, and a Latin version that Matthaei provided. I haven't yet discovered whether the Latin is intended to be Matthaei's translation of the Greek main text.

Apparently, Matthaei's work is of interest because it represents a collation of a few manuscripts that are now unavailable for collation (see the discussion of Matthaei's work here). I have not checked whether any of these now unavailable manuscripts were witnesses to Revelation. In any event, I include this collation by way of further confirmation regarding the state of the text of Revelation 16:5 in the manuscripts at the end of the 18th century.
