I'm thinking I have a never issued one as well. A friend and I bought them through a mail order years ago and I seem to recall they were less than $100. When the 2 boxes arrived I picked one and he the other to keep it fair. Mine didn't have a blemish, not a mark on steel or wood.
His looked like it had been used as a traction device for a tank...
I took the top wood off and unfortunately have misplaced it. Tula armory 1937 so It should have seen action but it's user must have been a desk clerk or the most careful Russian ever. All matching numbers.
