Yes, it's spelled correctly, the above link from Ventmarin says it's a small red used for commercial purposes.

And you can see from this general Google search above that Motelle has been used in studies for Root Knot Nematodes as well as Verticillium, and no doubt b'c it is a variety grown for industrial purposes as the Ventmarin link said.
I saw no references to it being a Russian variety, Tania doesn't list it and Tomodori just points the way to Ventmarin and while I didn't read all the links in the above Google search I didn't see a Russian origin mentioned. But lack of mention doesn't say that it might be, but if so I would expect to see some of the studies authored by Russian authors, and I don't see that.
it doesn't look like an heirloom variety, yes, an OP, and if listed at the Rick Center no doubt used by breeders or who knows what.
If interested, another place to look is the USDA PC GRIN data base.
But as I said above it looks more like a processing tomato, either for canned paste, or possibly tomato powder.
