COMPUTOR (Dealer: Jinta) – I heard this is an old wooden calculator, but don’t know what it was used for and also how to use it. Maybe it’s like a ‘soroban’ (abacus). I’ve never seen like this before. Quite an object. Early Showa period. approx. 32 x 23 x 4cm (12.59 x 9.05 x 1.57in)
Sold, Thank you.
