Hey there :)

Could you please measure the diameter of the shaft? Maybe it is a Kromer key.

Hello Thanks for the reply have measured the diameter of the round main shaft and its 5mm

Those are the same measurements as my Kromer change key. And the shape is also the same.

So there you have it: Its a Kromer key :)
