Balance 22 inch. Stamped 2190 and 30
Thanks for reaching out! From what I can see in your photos, it does not appear that the tabs have snapped off of the shoe. However, if the other balance does have a winged shoe, there is a chance the one of the balances in that window is incorrect. To determine which balance should be in the window, I would suggest double checking the balances from similar windows.
In regard to the stamp from the balance, the 30 is likely to mean that the sash is 30lbs but that is not a guarantee. To determine if that is the correct weight, you'll need to obtain the exact weight of your sash.
Please let me know if you have any questions in the meantime.
