A24 Ansonia Clock Company e22. 4

There’s a A24 Above where it says Ansonia clock Co. And below almost on the bottom it says E 22 and then to the far right there’s a number 4 big and bold, It says on the bottom John V coats October 21, 1925 just wondering what the A24 in the E 22 may mean? Any insight on how to rewind it to make use of it would be great thank you
