Sorry, but plombir isn’t USSR’s achievement at all. The “plombir” in USSR first appeared in 1937 produced by using US equipment after Stalin has visited USA and tasted the ice cream there. No ice cream was there prior to that. Next, the plombir’s name and recipe were “borrowed” (as many things in USSR) from French dessert “glace plombières”.

I'm pretty sure Russian Empire had ice cream. Google for long reads online - ubiquotous in late XIX century.
