Hi mate I have dug out the rest of the speedo for you due to your probs, it aint great It has paint on the face, the mph needle is snapped and well looks 40 years old . I can post a couple of pics if you like. My photos are poor though as you saw earlier. Someone might know if you can swap the speedle needle then if so the mech bit may be ok, But I do not know.
No probs mate, don't worry. My speedo needle has now broken so think that's the main bit I need - i'll see if I can pick one up from somewhere. cheers,~ Ade.
