This listing is for a Rare Antique 1932 Brunsviga Portable Mechanical Calculator Model 10. There is some wear from use, age & storage. I am unsure how this thing functions, so I don't know if it has any issues or if it is working properly. Please see all photos for condition and feel free to ask any questions.

***Sales tax of 7.75% is added to all California transactions. Please be aware that some other states have recently required that sales tax is collected. This is automatically added to your transaction by eBay and they send it directly to your state government. We, the seller, have no control over this portion of the invoice. Thank you for understanding.***
