Best I can suggest, to avoid being too long and repetitive, is to refer you to this earlier thread. Compare the movement there and check out the links in it for additional information.

Ken Robert's book, The Contributions of Joseph Ives to Connecticut Clock Technology, also shows the movement in a Silas Terry clock (p. 184, fig. 93). The movement is most likely a Silas Terry product.

I just re-looked at the articles in the thread I linked to. If I understand correctly, the style of movement you have, with the semi-circular EW bridge, was not sold by Terry but reserved for use in his own clocks.

That is a pretty neat movement.

I guess the general consensus is that it may be a SBT product. Similar movements with differences may be found in clocks by SBT as well as other firms.

I suspect they were SBT products.

For a nice discussion of these and other SBT 8 day brass movements, see this article by one of my favorite late scholars, F.H. McMillan:

Also see Dr. Taylor's discussion of these movements with round front plates and solid square back plates (you will have to scroll down some to find the relevant parts):
