1900 Winchester style B.B. Gun

I'd like to find out more information on a piece I have in my possession -- a 1900 Winchester style B.B. Gun which is cock and spring loaded. Its makeup consists of a steel barrel, caste iron body, a wood stock, and a steel butt. The right side of the body shows an Elk with some Oak leaves and various animals set in caste iron. The second side depicts Griffin-like birds and various animals. It has a caste iron plate that reads "1900".
