Kristian,
The pictures above are what I have now.
The clock came out of my 1975 C150 M.
I don't know if it works, I took it out right after i got the 150.
The face knob is missing, if you have yours you can put it on.
I will test it tomorrow for you.
Then send me your address and I will send it out. Try it, See if it works for you.
If it works, I'll take 25 plus shipping if that works for you, if not just keep it.
Maybe you can part it out, face plate is clean.
Mark
