Here is another great find! This is no joke, I have looked for these very same switches for as long as I can remember and finally found them in Germany. So what's the big deal? Well, these switches have been "NLA" for many years and the only other option I had was using the 'screw-type' connector switch with the 'texture/wrinkle' plastic knob finish. Not any more! I was able to purchase one "NOS" https://pbase.com/9146gt/image/136566771 and one "Used" https://pbase.com/9146gt/image/136566776
