Can anyone identify the second number stamped on the brass plate on this speedo?



The 'S434 - 10 - 41' is clear enough but stamped above that (upside down) is '444608'.

Is this possibly from another marque and is actually incorrect for a WM20?

Obviously not going to cure world hunger but in the endless search to find those rivets to count........

Ray, all the WD speedo's are interchangeable between makes. There are the period differences of course.
I just took a look under some of my speedo's with a mirror and torch. I have two with those plates. One is painted so can't read it. The other one is plated and has the same set of big numbers as yours but is dated 1-38. The second set of small numbers are below the date number and are different to yours.
I also think the little sectioned circle on the speedo base is some sort of WD date code?
I also have a NOS WD speedo that is probably late or Post war. I took it from it's original brown paper wrapping. It has no plate or circle. Ron

is that little circle a date stamp like you find on some cast or plastic items

If you look closey, there should be a punch mark or something in the appropiate month- year.
