Brunsviga Vintage Mechanical Calculator Antique collectable item

The vintage technology with the Brunsviga Calculator, an exceptional and partially functional piece of history. Extraordinary mechanical calculator for collections of enthusiasts and anyone who appreciates the gadgets.

The machine is in very good condition, it's partially working fine, except the rod number 6,7,8 seems jammed, needs service, but other than that addition and subtraction working fine on rod 1,2,3,4,5 and 9 and 10. All lever function correctly when tested. This is my father collection item and it has not been used for very long time.
