Alps Electric, 1960s–1980s (rev. 2a.i, Nov. 2018)
The Alps logo is derived from a print advertisement in Electronic Engineers Master 1983, with corrections for ink spread based on careful observation of some accurately-moulded switches.
The black-on-white RFT logo is derived from the Passive elektronische Bauelemente ’79|80 catalogue. Both RFT logos are rough approximations due to a present lack of high resolution image to use as a basis, as well as the usual lack of consistency from one version to another. The red EB logo uses also a rough guess at the colour.
