I don’t think you can update this post to bring it back to the homepage, for more eyeballs. So, yes, I would recommend to repost it, with the new images, and maybe with a link to this thread.
Most specimen books and other references about metal type are concerned with either foundry type or designs made for hot-metal typesetting machines like the Linotype or the Intertype. Brass type is used by bookbinders, as its harder than lead alloys and doesn’t wear off so quickly when used for stamping. It’s a world of its own, and pretty much separate. My understanding is that most designs produced as brass type were adaptations of printing typefaces, sometimes under pseudonyms (see this page: Javery/Porter/Jefferson = Cheltenham, Sterling/Sutton = Stymie, Gale Script = Murray Hill, etc.). But there certainly were some original designs which only exist as brass type, too.
