At the Kalashnikov museum in Izhevsk, one of the exhibits includes this item:
It is a yoke-shaped square bar of light, unvarnished wood, roughly 100 cm long, with rounded corners. There is a hole about 5 cm in diameter drilled vertically through the center of the bar. The two raised ends of the yoke are each pierced by a rod of dark metal, which splits into four smaller rods which spread out at a 30° angle and extend about 20 cm high. In one of the split metal rods is cradled a small piece of rough wood, with black scorch marks at both ends. There are also some scorch marks on the yoke, directly below one of the metal rods.
The exhibit shows objects from Mikhail Kalashnikov's mother's household in the early 1900s:
I recognize a spinning wheel, bowl and spoon, sewing machine, several pieces of woven fabric, and a small vase with some dried flowers.
What is the yoke shaped object called and what was it used for?
