Finally obtained an M20 Speedo, and it will naturally need some work. I have included a picture and have a question on the bezel ring. There is a rivet like pin which retains the ring which I am not familiar with. Is it just a pressed in pin or ??. It has to come out for the ring to unscrew. Any suggestions? %20void(0);

There have been a couple of threads about these anti-tamper seals.

Thanks Ian and Rik, I must have missed the thread. I will pull the rivet and see what needs to be done. It is nice to have an untampered one.

There are some small markings on that rivet. If you chop it off with a sharp screwdriver you might be able to glue the head back with a blob of Araldite. Ron

Thanks Ron, I was just thinking the same thing, maybe drilling the center rivet and saving the washer.

I have the speedometer apart now and am quite lucky. The one screw that holds the escapement in had fallen out. The odometer only shows 2100 miles so mechanically everything is in good shape so far and I did save the Smiths seal.
