Again from Ed Pitt: “The two snare drums in your photos are both what’s called “pioneer” drums. They were marching drums made for the Young Pioneers, the Communist youth scouts. Really cheaply made stuff, either tin or cardboard shells. They are usually about 10″ in diameter and were never used as part of a drum set. The bright read drum is newer, the thinner dark red one is older. Makers unknown, they were made in various toy factories and such in different cities around the country, hence the minor variations. Drum sets in the USSR were made in two factories: EPOIMI (Engels Experimental Music Instrument Factory) in Engels and RMIF (Riga Music Instrument Factory) in Riga.”
