Building a replica, but can't ID the movement

Hi - well as the title suggests, I'm building a replica of a mantel clock that has been in our family since the 1960's. It was included with the purchase of a summer cabin in Maine. Here's what the pictures don't tell you:

Westminster chime, progressive, (plays 4, 8, and 12 notes on the quarter, half, and three quarter hour).

Four chime rods & hammers.

I removed the movement to look for any markings, but could not find anything.

ANY help is greatly appreciated!
