T\)e Steel Tl^ioKer. 



When vou talk about labour-savins: niachiner\', vou generally mean labuurer- 

 '•">« 932 ci. - macninery, don t you ? You mean machniery which substitutes steam power 



. iscle power, or mechanical speed and precision for manual dexterity. 



" But manual labour is the cheapest kind of labour. 



Did you ever hear of a machine that could save brain-labour ? A machine 

 which, within limits, can think ? 



There is such a machine. It is called the Urunsviga Calculator, but do not let 

 the name mislead you. You know all about adding machines, but this is not one of 

 them. With brains of steel it perforins every operation of arithmetic. 



It s Tbougbts- 



It works out iiuilliplicalioiis and dixisions, proportions, rates, percentages, 

 everything. It ^is ([uile indifferent to the subject inaller. It will take on an invoice 

 extension or a length note, a liinlier calculation or a currency conversion with 

 equal readiness. 



It will give you the result in a quarter the time that a human reckoner would 

 lake. And it caunot make a mistake. Its mind never wanders ; it never forgets a 

 ligiirc or makes a slip in its multiplication taljle. 



Instead of saving the time of the l^s. n week man, it saves the time of the ^4, 

 /'n iiiil /"so a week man. . 



Its LooKs. 



It is a little desk instrument, liandsomc to look at and handy to use. 



The special light model is called the Hrunsvigiila. It weighs 7 li)s. , is the size 

 of a small hand camera, and works in a whisper. 



There are _'ii,0(iii Hrunsvigas in use in the world. This is what uiie firm says 

 of it :— 



"The Brunsviga Calculator Machine did in exactly v'- minutes, absolutely 

 correctly, certain pro-ratiiig which our f;istest accountant could only accomplish 

 in .V5 minutes of solid work."
