This is an excellent reproduction created by Hollywood Speedo. Date Code 1/70. Since I now have an OEM and NOS part, it will probably be offered for sale.

For reference, look at the VDO 250 Km/h Speedo installed in the very famous #40 Sonauto 914-6 GT https://pbase.com/9146gt/image/25692324, now look carefully and note how this particular gauge has an incorporated blue high-beams indicator at the bottom-center of the gauge. Also, note the red stripes over the 50 km/h mark on the dial, certainly a bit different than similar other speedometers I've found, including the one I had reproduced. I may have to do this again if I cannot find one exactly like it.
