In comments to my post on Beza's Greek New Testament, Stephen C. Carlson (Hypotyposeis) writes regarding the bibles.org.uk site:

That web site is very interesting, but there's some important 19th cen. editions of the GNT are not there (e.g. Westcott-Hort, Lachmann, Griesbach, etc.). Do you happen to know of any sites that has scans of any of those editions?

I don't know of other sites offhand apart from the TC Ebind Index. (I'm guessing the bibles.org.uk dude lifted stuff like Tischendorf, von Soden, Sinaiticus, etc. from that site.) 

I've got a print copy of Westcott-Hort, so that's not a problem for me. But the others would be nice to see. If anyone has info on any PDF facsimile editions (that is, scans of the actual documents, not transcriptions and re-typeset editions) I'd love to know about them. I'd also like to see early Nestle editions (I have a 1912 Nestle, which is the ninth edition if my Latin guessing skills are any good), Tregelles, or just about anything else out there you might know about.

The same goes for critical editions of any of the early versions (Syriac, Coptic, Ethiopic, Latin, etc.). I'd love to see 'em if you know where they can be found.
