Green-grey electro-mechanical calculator, with accompanying power cable and manual. Calculator itself is largely square in shape, with rounded edges. Detailing in in silver metal, and all moveable parts are made from dark red plastic. There are several sections of the calculator which are as follows, going from bottom to top. There is an extruded metal handle near the base of the calculator. Above this and to the left are six push buttons, with the symbols + and -, and the Roman numerals I,II and III. With these, there is a slider, which rotates through various mathematical symbols. To the right of this, there is a set of seven sliders, which can rotate through the numbers 0-9. There is an additional slider at the bottom of this which can choose which of these sliders is in action. This part of the calculator is marked with the Roman numeral I. Above this is a part of the calculator which can be pulled out by way of a finger hold, and which is marked with the numbers 1-11, and is itself labelled with the Roman numeral III. Finally, above this, there is another sliding element marked with the numbers 1-6 and labelled with the Roman numeral II.
The calculator comes with a power cable in the same colour as the body of the calculator, a black end to be inserted into the calculator, and a white plug. There is also an accompanying manual entitled "INSTRUCTIONS FOR USE: BRUNSVIGA 11E/11S"

Description
The Brunsviga 11E electro-mechanical calculator was the successor to the Brunsviga 10, which had a mechanical, stepped drum mechanism. The 11E, which was released around 1952, has an additional register, bringing it to an 11-digit register. The E represents the electric motor that was a new addition to the calculator.
