Nice to see this thread again , hosman321 !
It appears as if there are 2 'stops' (for a round metal fence/etc. pole) cast into the interior of the hollow equestrian item ... is this so , or are my eyes talking before my brain kicks in , again ?
From your side-by-side photo , it appears as if the 'first' solid head has traces of sky-bluish paint , while the new-to-you head is a (?) reddish or weathered white color ?
You could certainly test for lead in the paint of both , which might help/lead to determine age &/or non-U.S. origin ....
As 'post toppers/finials' these also might have been used , in conjunction with lengths of chain , for gardens/walkways/amusement rides/horsetrack gardens , etc .
As before , hands-on is best for I.D.-ing .... long research project , hosman (kinda like trying to tap-dance in a tar-pit) !!!
Then again , slow & steady has won some races ....
