They say imitation is the sincerest form of flattery... While you may think you are looking at a mid-50's Vespa, these two scooters are actually the Soviet-made Viatkas. The Vyatka was quite similar to the Vespa, but was heavier and slower. It had larger wheels, and it looks like from the photo above, a grab handle at the back to pull it out of mud and snow. All in all, the Soviets could have done a lot worse than their Vespa clone. (The later models of Vyatka were Soviet designed. Though they were utilitairan, they were style-less boxes on wheels)
As far as I can tell, the Vespa-clone version of the Vyatka was made from around 1957 to 1965. Supposedly three-hundred thousand were made. If true, that is a pretty huge number, even compared to the real Vespa. However, consider the harsh Russian climate, poor roads, and legendary poor build quality of Soviet vehicles... and as you can imagine, not many seem to have survived. A handful of these have made it to the US. Have never seen one in person, but there was actually one for sale recently in Utah. I can't say that I would want one myself, but it is a very interesting side-note on the Vespa story.
