Art 1642 Divider RT 42
(later article 532 142)
Lenght of compass: 145mm,
for distances up to 200mm.
matt nickel-plated
In transparent case with blue inside.
Compasses with blue inside of box are the earliest versions from early 1970s.
What I gathered red boxes were used for chrome glossy compass sets, and blue for nickel plated matt versions.
