Sekonda is probably a useful starting point. The brand is (and apparently alwys has been) British owned and launched in 1966. Almost all Sekondas from that early period appear to be stock Soviet models rebranded (apart from a very few that may have been cased-up in the UK). The intended market seems to have been primarily the UK and secondarily the British Commonwealth. Sekonda-branded Poljots have the same dial markings with only the name changed.
Two things to be learned from that:
1. There are unlikely to be market-specific variations to the logo
2. Whatever version of the Sekonda logo found on the earliest Poljot-made Sekondas is likely to reflect the standard font usage by Poljot at that time.
