For your consideration, here is a Sharp ELSI-MATE EL-208 Small LCD Calculator.  It has an early serial number, 010. It takes a 9 volt battery. It is noted for for this and having a large battery compartment.

The calculator has been tested and it works great. It has some wear on it. There are some glue spots on the back of it. There are some chips by the coin slot area. The battery compartment is clean. Item pictured is the actual item up for sale and comes from a non-smoking household. (116.63h-.8hc)
