I'm trying to put order in what I find in some books:
According to 'A-Z of Racing Cars?:
'
Stella III': An obscure Russian 500 car of 1951. All that is known is that it had a rear-mounted ZIS 342 engine.
'
Svezda': The Svezda Salut was a compact 1952 Russian 500 car which looked not unlike Cooper. Press releases from the URSS suggested that it was a serious F£ car, and photographs showed one receiving the chequered flag at the end of a 'race'. (...). It was all propaganda, however, and magazines which published photographs of the race winnning Svezda suggested, perhaps correctly, that it was a steged picture. Photographs of the 350cc Svezda Record car (...) were also released but nobody took them seriously.
According to a well documented site (that you heve to know
):
Zvezda: The first Zvezda (star) was built in Russia in early 1951 and looks remarkably like the Salut of Derkovskiy and Peltzer. Press releases suggested that it was a serious contender and a photograph was published which allegedly shows one taking the chequered flag however it appears that this may have been largely Soviet propaganda and no car ever raced outside of Russia.
The same car, or possibly simply the same name, appeared again in 1957. The Zvezda 500 was designed by Alexander Peltzer and three cars were ready to compete in 1957 USSR Championship. All of them had streamlined bodies and two-cylinder motorcycle engines IMZ-M52, giving 35hp @ 7000rpm, placed behind rear wheels. Independent suspension for all wheels with springs was used. The frame was made of wide tubes again, an idea borrowed from captured Auto Unions. In 1959-1960 Zvezda 500 cars took one gold and two silvers at USSR Championship rounds. In 1959, Alexander built a second 500, the Nami041M
Salut:The Salut and Salut-M racing cars were the work of Mihail Derkovskiy and Alexander Peltzer. In the spring of 1947, Derkovskiy became a director of a construction bureau for racing cars in USSR and began work on the Salut racing car and also the Pioneer record car.
Now with your reply it makes sense:
In the book there are just the Zvezda 500 (Stella III) and the Salut (Zvezda).
In the site there are the Zvezda 500 (no mention to Stella III but there is the famous pic with the chequered flag) and Peltzer's Zvezdas under the Zvezda name and Peltzer's Salut under the Salut name.
