There is a book in this tale.

The Jupiter-3 lens design is that of the Prewar Carl Zeiss Jena Sonnar as
continued, Postwar, in production by the Communist CZJ works, though
slightly different from the western Zeiss-Opton or Carl Zeiss lenses.

Early Jupiter-3 lenses were almost certainly produced at Jena in Germany
from Zeiss parts.  Quality control on the Jupiter-3 line was always tighter
than that on many of the other Soviet lenses.  

It has been my experience that the finest and most consistent lenses of
this breed are those produced by the ZOMZ works, these being relatively
late lenses finished in flat-black paint.  Look for serial numbers
beginning with 83.. or 84.. or the like, up to 94.. or so.  

A solid Jupiter-3 is a magnificent lens:  the design dates from 1932 and
was one only equalled by Leitz with its second version of the 50mm
Summilux.  A good Jupiter-3 will certainly overwhelm a Summarit in all
optical parameters, stalwart though the Summarit may be.
