Yes, a Browning 16 gauge manufactured around 1925 could be either an Auto-5 or a Sweet 16. The Auto-5 was introduced in 1902 and the Sweet 16 was introduced in 1937, so a gun from 1925 could fall into the transitional period where both models were being produced. It would be best to check the specific markings on the firearm to determine the exact model.
