Possibly - but I think that would have been an earlier Jupiter 3 - not that there would have been much different other than a sort-of styling chamge.
"MZ" Mark Dicker had some experience of Russian bikes & warned me off them - mainly due to the miserable materials quality and slip-shod manufacturing. I almost fancied getting a Jupiter 3 at one point, as they are similar to the mid-50s DKW RT350 twin that are not common here and very pricey - Mark reckoned that the Jupiters were completey clapped out if they managed to make it to 10K miles due to the poor materials used.
He had a Vostock 175 at one point that he described as being "so bad it was comical". A fellow apprentice bought a new Vostock 175 while we were at college in the late '70s & it would go rusty during the day while parked if it was raining.
I replaced the sidecar light cluster on the "Xmas snow scene picture outfit" with a new one and it was absolutely dire quality - the die-cast base on the original just crumbled away & the new replacement wasn't much better. I had to be very careful tightening the lense screws, as the casting threads would have stripped before the plastic lense broke.
There is a (very well produced) YT video of a Russian guy rebuilding a Jupiter 3 from the mid-'60s & he complains about the dire standard of the NOS parts he bought in for it. The "engineering" diplayed in the original product is absolutely minimal - his rebuild is of way higher quality than the original factory managed.
