early Adding machine

early Adding machine
Product Description
This is an early adding/subtraction device ( mid-1900s ) that was used in my classes as I taught about early computing devices.
There are 2 of these, although each is made by a different company.
The price is $22 for each machine, which includes s/h.
These are the only ones I have of this type but I have others in my TPT store.
