Bonjour CPN,
well, here the facts we know. Before Linear-A there was Linear-B who clearly had its sets sculpted and manufactured by Streletz team.
From some names on the Linear-A site you can guess ties to Ukraine.
What is indeed interesting is to follow the improvements in sculpting. We have discussed in the past that Streletz has probably 2 sculptors - there seem to be 2 styles, and how else can you keep the output they have?
On the VK site (type of Russian Facebook) people discuss sculpting a lot and maybe they know more. Surely Streletz people discuss at least with Haron / Redbox / Orion - about future sets, periods to cover, etc.
Personnally, it seems to me that there are 2 sculptors who have consistently improved - there is still style of the original sets (I have recently painted figures of the GNW - some of the first sets!, and Marvin has shown his contributions). It would be worthwhile to do a comparative study on this.
