Andrey, I have seen that picture before, and the one I have as "Snickers" is much smaller, but who knows, maybe it's just my growing conditions that effect the fruit size.
And yes, there are Rozoviy Flamingo plums, and there's a heart one from Popenko, which I recently got. There's another RF and it's pepper-shaped and striped.
The Ukrainian RF is a fat paste/heart one.
bower, I'm in the same situation you're in
but I'm willing to grow your Black Pepper, because the Russians have a "thing" for pepper-shaped tomatoes.
I also have 6 seeds of Kubinskiy Pertsevidniy and I got a hold of Pertsevidniy Cherniy from Denis Terentiev's collection.

Scott, do you have room to grow them all out and compare? If so, I will send you some seeds.
P.S. Black Icicle is a totally different variety, it's a smooth elongated plum.
