Brass Bell Clock J.E. Caldwell

I have an antique mantel clock manufactured by J.E. Caldwell. With the research I've done, it appears to be a very rare clock. I do not know much about how the clock works but the internal mechanism that allows the clock to function is no longer working based on observation.

The exterior is covered with different scenes and ornate designs. It has a Latin phrase cast into the bell, “SPIRITU TOU DOMINUS VOBISAUM". The dial apears to be porcelain and all the numbers are intact along with the hour/minute hands. J. E. Caldwell was a Venerable American silversmith from Philadelphia. In 1839, James Emmott Caldwell began to supply wealthy Philadelphians with stylish European jewelry, silver, and objets d'art. The movement is signed E.P. Paris.

I found the clock in my grandparents basement. Both are deceased and I can't find any connection as to where/when they purchased it. I plan on getting it appraised with a certified antique dealer/appraiser. I stumbled across this forum and decided to show others what I have and possibly find more info on it. If anyone has anything to share, please do!

Thank You!
