Relay/Ricoh



Japan.

Relay was established 1951 and later amalgamated with Ricoh. This company appears to have made a number of slide rules which carried other companies brand names.

Other brands made by Ricoh/Relay



The Relay/Ricoh group made a range of slide rules under other names. Sometimes this was a slide rule made to the specific requirements of another company which produced slide rules and and in other cases it was a distribution agreement. Some of the brands/rules suspected or confirmed are:
  • Alvin (models beginning with1000)
  • Charvoz (SR 201 and maybe others)
  • Compass
  • Dietzgen (all B series, maybe others)
  • Eagle
