Here are some good close-up photos of the different variations of the 4-Way Emergency Hazard Flasher knobs. Prior to the change in 1972 and for a correct 1970 and 1971 factory 914-6, the red plastic insert for the emergency flasher knob had the word "Emergency 88" with the "VW" logo at the center, not a 'triangle' logo with the word "Hazard" or anything else https://pbase.com/9146gt/image/150931182 - The following link shows the 914-6 correct 4-Way Hazard switch installed in the famous factory built Sonouto #40 914-6 GT https://pbase.com/9146gt/image/25692332

Here is an interesting plastic insert with just a triangle-symbol, no text https://pbase.com/9146gt/image/150904032

I'm still looking for the OEM, NOS switch itself. The one I have works fine, but it is used and would like to upgrade it with new. If by chance you have a "NOS" swtich available for sale, please drop me a line at ajserrano at msn dot com. Thx!~
