Most of the supply houses will have the cherub. The base, if you know a woodworker they might be able to turn a replica. Your glass looks more like a New Haven than an Ansonia. The one I have required a donor case much like yours does. Worst case, you could have the base replicated.
Hope this helps.
ps, I will look in the parts shed, but I think what I had is gone.
I believe the glass print has been added on. It does not look original. Nor does the dial. It says westminister surrounded by bells. So this clock is turning out to be a bit of a Frankenstein. Guess it wont hurt to build my own base.
