Walther TASMA Calculator
Early WALTHER TASMA Listing Machine
"In 1931 the rather strange looking machine ... was added to the range. This machine was designated the TASMA and worked as a print out calculator. It appears to have sub total and grand total keys as well as a clearance key. Each time an entry was added to the keyboard the large crank was pulled forward adding the information into the accumulators and printing the keyboard data on to the paper roll."
