Curta mechanical Calculator Type I with can and 3 manuals in MINT, UNUSED state

Description

Up for auction from my personally collection is a
gorgeous Curta type I mechanical calculator that was bought new from an employee of Contina AG (the manufacturer of the Curta calculator)
It has been kept in its case
and has never been used except to test it for functionality sometimes to keep the lubrication working.
I was told that this Curta calculator having been made as a factory sample from Contina AG. It was not intended for sale and therefore has no serial number. It can be assumed that this Curta calculator was produced in the mid-sixties.
This Curta calculator is in perfect
working state.
All of the mechanical parts function as they should. It operates correctly in every way even with negative crank turns, the ten-carrying mechanism works correctly in every position of the carriage.
I performed the testing procedures outlined on the curta.org website and everything is how it is expected.
This curta calculator is in factory new state with no signs of use. With a used Curta, one normally finds concentric marks on the top part of calculator where the pull ring has been used. I have attached a close up photo of the top of the Curta to show that you find no such marks on this Curta.
This Curta calculator comes complete with
its original metal can
the operation instructions in English language (46 pages)
the computing examples in English language (51 pages)
a fold out step by step manual in English language (2 sided, 20 pages)
The operating manuals are high-quality reprints in new condition.
The Curta calculator was affectionately known as the "pepper grinder" or "peppermill" due to its shape and means of operation.
It was also termed the math grenade due to its superficial resemblance to a certain type of hand grenade.

I have taken great care to show the device in great detail.

This Curta Calculator comes from a pet and smoke free home.
