Comrade Desantnik will surely have something to say about your hoarding.
If you want the 'best' in Soviet rangefinders then the ultimate one is the KMZ Kometa (Comet) which was a demonstration camera at the 1958 World Exhibition
To be very serious for just a second, people do like to rubbish Soviet design and manufacturing but they were very capable of producing outstanding pieces of equipment and technologies but only when they needed to.
And thats the key, it was good when it needed to be good. If it didn't need to be good, the resources were not expended on it.
