Tool for Ignition Tumbler Help

[bigfredb]

I need to remove the ignition tumbler in my 83 300SD.

I have read through all of the threads which tell how to do this. However, I can't seem to find a tool which will do the job.

I have one of the 'single hole tumblers'. I have tried paperclips, but they don't fully work.

In one of the threads, it talks about using a 1.25mm allen wrench.

Does anyone have a picture of what the actual MB tool looks like?
Does anyone know where to get a 1.25mm allen wrench or the actual MB tool? (I've looked and cant find anything)

Please help!
