Letterpress Titling font, maybe early 20th Century

[George Thomas]

I've come across something I cannot identify in numerous American foundry books even though it is quite unusual. A metal caps-only font which I suspect is late 19th or early 20th century. No pin mark or other identifying marks. It has the usual nick and groove, although the groove is off-center and seems to be deeper than normal.

Appears to have been called Fifth Avenue Monograms (ATF), according to this post on the WhatTheFont forum.

And it has been digitized.

@Kevin Thompson Thank you! It never occurred to me to look at monograms. The closest thing I finally found late last night was Head Letter No. 2 from Keystone. It appears to me the ATF monogram type was closely based on that design.
