1940s ~WW2 Vintage German MEGA Ohmmeter Excelsior-Werk Rudolf Kiesewetter Wooden

Description

RARE Vintage MegOhm / Insulation Meter
Beautiful and VERY RARE Vintage Megohm/Insulation meter from 1950s.
I don't have an exact production date of this device, but the model  was produced from 1935 to 1958. I think this particular device was probably made either about 1939-1941 or between 1945 and 1955. The information for the production run of this model (1935-1958) was taken from two different sources.
- Made in Germany by Excelsior-Werk - Rudolf Kiesewetter.
- WOODEN BOX in IMMACULATE condition.
- High precision measurement device -- precision class 2.5 % .
- Can be used as Insulation meter, as Mega-ohm-meter or as AC Generator (up to 500 V AC).
Condition: EXCELLENT outside condition. No scratches, no dents, FULL SET - no parts missing !
User manual is printed on the inside side of the lid.
NEVER OPENED for service - There is factory or maybe a calibration SEAL (shown on photos).
The device was owned and stored in a STATE-OWNED company until very recently.
Has one calibration mark from 1960. Only one calibration mark means the device most probably was not used (or used very rarely) between 1960 and now.
TESTED to be in working condition - I connected a 20 Mohm resistor, measured it and the Megohmmeter provided a reasonably close result. Of course I can't guarantee how precise measurement is because I don't have anything close to compare it with (and I have not worked with this type of MegOhmmeter before).
- The lid opens and closes like new. No gaps and no slack when the lid is closed - seems almost like it makes an air-tight seal -- please see second-to-last photo !  To put it mildly - I'm IMPERSSED !  I'm sure the door seals on a current new Mercedes Benz S-class will not be able to reach this precision making!  :)
- I think the device was made in the late 1940s -- I really worship the mastery of the company and the person who made the box and this beautiful piece of equipment !
- Leather handle - in excellent condition -- and it seems to be the original one.
- Hinges - in perfect condition.
- Metal Handle - in perfect condition.
- Lock - in perfect condition.
- One of the rubber feet seems not to be an original one - the difference is barely visible.
- No cables are included
- Was received in this condition, was not opened (there is a factory seal), no restoration work was made and it didn't need much cleaning too.
