Answer
Without a model number it hard to id the gun exactly.
Western Field was the house brand for Montgomery Ward.
The "Browning Patent" was were model 520, 520a, 620 made by Savage Stevens for Wards. It can be Western Fields Model 30, M025, M35, SB033, & SB33.
If you email a clear picture of gun I can likily narrow it down by matching it to reference pictures.
Exact dates are impossible but production dates are possible.
