The barn abacus is made of wood and framed in brass.

Size 39 cm by 24,5cm.

Unfortunately the condition is bad. Bronze plates are partially broken off. The tree has cracks and other damage. The metal pins may have been changed or restored, they are crooked and loose. Look at the photo. The abacus have the signature of the owner N. Karpukhin and a number on the other side, which makes them a rare collectible regardless of condition.
