(asap with this one - sitting on the sofa with my car in pieces in front of me

I have done a few posts similar to this but cant find them so need to ask sort of the same question now I have found something interesting...
now just need to know the best thing to do...
Basically, I was under the impression that my mini had come from Germany, however I was told this by the seller, so was always unsure.
ANYWAY... I got bored tonight so I thought id have a play with my speedo, fuel gauge and lights etc because they weren't working right.
so when I took my speedo apart, from this:

I found this:


so what now? the fact that the original speedo is in KPH means that the odometer is in KPH too... so if I keep the cream front on, the odometer will read wrong... (as it will read in MPH).
Any ideas what I should do?
Cheers
