A rather late machine for my interests, but when it appeared on German ebay, I just had to buy it. Why ? Because the address for the shop where it was bought is literally aroudn the corner from where I grew up. It is an example of the budding office machine industry in Spain in the 1940s. The same machines were also sold under the "Select" brand, and the fatory was taken over in 1945 by ICE, another Spanish calculator brand. This one is a very nice dark green, has been well used, is very light in action, and pushes all the right buttons - handy one-hand carriage transport, easy clearing of all the register ... really a very well thought-out solid machine. It seems at some point, someone mounted it on door-stoppers though.
And the distributor ...
