Now that I've had time to do a little looking about, I can also say that the Bulletin contains much information on Manross. Perhaps a good place to start is Lee Smith's article, "Elisha Manross: The Clockmaker's Clockmaker," in the October 1993 Bulletin (see link below, but you must be an NAWCC member signed to nawcc.org to access it). A picture of your movement can be found on page 544, figure 1.
Well, perhaps the clock, like the movement, is by Elisha Manross. Not much of a label to go on, but Manross did sell clocks under his own label as well as sell movements to the trade. Curious to me is the glass, which seems to place Magdalen College in Germany. Of course, it is in Oxford, England. The glass has been found elsewhere, in this Birge, Peck, & Co.:
Well Steven, it's beyond me, if you think it's a Elisha Manross clock your word seems gospel with me. Too bad there isn't a label on the inside but I realize that we can't have everything. I'm just excited that you've educated me to the place we're at now. Is there anywhere a replacement label could be found? If anything more comes to the forefront please pass it along, I've become interested in the man of Elisha Manross.
Thank you for sharing your wealth of knowledge,
