The Soviet versions of these dials were only made for around four years maximum (probably less) and the USSR dials are getting harder to find in reasonable condition especially the Zakaz versions.
Interestingly the only official images that show Soviet tankists are on the 1992 Vostok calendar printed in the last days of the SU, the 2002 Vostok calendar (November) and on the leaflets put into the large boxed sets for Italian export, none can be found in actual Soviet catalogues, don't know why...
