This was sold by Sears , made by Stevens between 1912 and 1942. It was not made by Browning.
This model was made by Daisy for Sears. It's the Golder Hunter model 98 made in 1958. It's very simular to the Daisy model 141.
This BB rifle, not gun, was made for Sears by Daisy air gun Co. In reality it is a Daisy Model 1894 carbine, octagon barrel. it was made between 1969-73 it was a "Replica Centennial Rifle."
The El Dorado is a variation of the Daisy model 880 made, I believe, it was made sometime between 1972 - 89
Both Sears and Crosman made air guns for Sears under the Sears JG Higgins brand name. Any air gun made for Sears by Daisy started with "799." any air gun made by Crosman for Sears started with "126." as the model number. The following 5 numbers identified the exact model of the original manufacture. Unfortunately most of those crossover records have been lost over the years. Your air gun was made by Daisy. This I am sure of. I found a photo on the web of Daisy model 799.19031 and was able to identify it as a Daisy model 25. There are 58 different versions of this mode starting in 1914 up to today. I think yours is a variation made between 1952-1955.
Check it again and make sure it's not 126.102940. If I'm right it was made by Crosman for Sears and is a model V350 made from 1961-69. It's a push barrel loading BB rifle.
Old gun catalogs, old Sears & Roebuck catalogs.
I believe your Sears BB gun may be made by Daisy air gun co and I think it is a model 1894 Daisy ( It looks like a Winchester 3030). Daisy offers a service to estimate the value of old airguns. see the link below.
