Serial Number Table Last Edited: 10/30/16 01:09
NOTE: dates shown are JAN 1 unless noted, so the serial number shown is the *first* serial number produced the given year. Exceptions are serial numbers preceded by "up to"(where you can assume that the numbers reported in that subsection are DECEMBER 31, END OF YEAR NUMBERS) or rows where a month is given in the month column. If the serial number is shown as a range (xxxx-xxxx) it indicates that we know the entire range of serial numbers for the given year.
Designed by Arpad Krejniker and manufactured by
A. Ney, Ritterstr. 123, Berlin, Germany, who
produced the Helios-Klimax since 1914.

|1925-1926||The first machines had a double-sliced type segment. The
slices were at the upper and the lower side of the segment and 2 kinds
of type-levers were used.
This segment was replaced by a usual single-sliced segment before serial number 1260, at least s/n 1261 has it no more.
And now we know this segment change happened before serial #1044, because 1044 doesn't have it either.
|Only about 3000 machines were produced and the factory was closed.|
