Curta
Type 1 Calculator (FIRST MODEL)
This is a very early and very rare first model
Type
1 Curta calculator. The serial number is 5714. That would
date this within the first couple of years of manufacture back in the late 40's. This
unusual calculator is in excellent condition, fully operational, and shows little sign of either use or abuse, just
a few storage dings on the outer case. The Curta calculator was invented by Carl Herzstark while imprisoned in a German concentration camp during World War II.

This interesting design calculator was the top of the line and immensely popular before the advent of the handheld electronic calculator essentially made them obsolete in the 70's. The last ones were made up until about 1970 and all told about 150,00 both Type #1 & Type #2 models were made. Today they are highly collectible pieces, and are an important example of calculation technology in the scheme of things.
This example is in excellent condition and operates flawlessly. The body is very nice and shows no wear or tear and there are just a few minor scuffs on the outer metal case. Note the design of the column levers and how they are different from later examples. The provenance I can offer is that this example came from Brazil and a college professor there was given it by a architect / engineer back in the 50's and it has sat in a drawer since then.

though ended it reign as the calculator of choice for use, and began it
accent into the realm of one of the most sought after of collectible
calculating devices. These vintage calculators are very collectible

top of the line calculator in its day and

The Curta calculator was invented by Carl Herzstark while imprisoned in a
German concentration camp during World War II. This example is in good cosmetic condition but operation is spotty. It will zero out but at least one of the number slides is stuck, and the operation is erratic seemingly working at times, and then jamming up and become hard to operate before settling into a position where it can be zeroed again. I am not sure if this means it needs to be repaired, or just cleaned and adjusted. There is no case.

They were
put into production shortly after the WWII ended. This example is in super cosmetic condition, but does not operate properly and is jammed up. In addition to the top ring not wanting to revolve, some of the number slide controls are stuck It must have happened early on and the owner simply put it back as it is still in its original metal case and original cardboard box with 3 pieces of original paperwork. The condition seems nice enough that this example would warrant the cost of a repair / inspection by one of the Curta repair places that can be found on the internet.
