This rocket paper model is a Proton-K (also designated Proton 8K82K after its GRAU index, 8K82K), a Russian, previously Soviet, carrier rocket derived from the earlier Proton, the paper model is created by L.Cherkashyn, and the scale is in 1:96.
The Proton-K was built by Khrunichev, and launched from sites 81 and 200 at the Baikonur Cosmodrome in Kazakhstan.
The maiden flight on 10 March 1967 carried a Soyuz 7K-L1 as part of the Zond program. During the so-called "Moon Race" these Proton/Soyuz/Zond flights consisted of several uncrewed test flights of Soyuz spacecraft to highly elliptical or circumlunar orbits with the unrealized aim of landing Soviet cosmonauts on the Moon.
