Yes they are VDO and I like them fine. They work better than most gauges I have had in the past. The Speedo is especially nice and the easiest one I ever had to set and keep acturate.
Yes the speedo reads in both MPH and kilo (In Yellow). The face of the gauges are glass not plastic.
This is probably the best photo of them I have:
