I recieved what appears to be a Smith-Corona Add Lister from a friend whose grandfather was throwing it out. I am not sure its worth, however, I am willing to sell. It looks almost identical to the Smith-Corona found here: http://www.vintagecalculators.com/html/smith_corona.html however, it does not have a row going up to 11. The calculator does have a pull handle, still works (though it needs an ink ribbon) and is in better shape then the one pictured at the link. Any information or bids would be welcomed. Thanks!
