Second Generation Simplex 2903-9101 Strobe Plate + First Generation Wire Lead Simplex 2901-9833 Test

This is a test of my second generation Simplex 2903-9101 strobe plate paired with the older wire lead 2901-9833 horn. The difference between the second generation and third generation 2903-9101 is the second generation circuit board looks like the third generation, but has the same circuitry as the third generation, and has no potentiometer, so it still flashes fast (around 120 FPM) and is slightly brighter than the third generation. Basically the third generation is the model most enthusiasts are familiar with. The only difference between the first and second generation is the first generation has a wider circuit board.
