This was introduced in late 2019/early 2020. There was an initial run of 100 and they were pretty much immediately sold out. It was sold with a solid bar and an open comb base plates and there was an option to buy a Titanium handle. They are pretty highly thought of because they are rarely seen on the BST forums
Originating from Russia, its based off of a Gibbs, also seven parts plus the extra base plate.
And just because I prefer shorter handles, I turned a shorter Stainless Steel handle for mine.
