I've had this for 10 years. It does not fit my sons CD auto. I can't for sure remember but I believe this one was made just before the model of gun we own. Pins do not quite line up with the later models they made. Model # on this one is 16460. If you think you can use it and are willing to pay for the shipping, it's yours. I think I could ship it 1st class USPS including padded envelope for $4.25.
Do you still have his mount?
