How to get driver's side mirror unfolded on 1993 Mercedes-Benz 300SE

I made the mistake of thinking my 1993 Mercedes 300SE had manually folding mirrors. Pushed it in to clean the insides and will not pull back out (tried the switch - just clicks but won't budge even with a few taps).

Is there a MANUAL way to pull the mirror back out without dismantling? - Alan

Perhaps swing bye the Mercedes dealership and see out of courtesy if would have a quick look at the car or show you how to get the mirror to return to its normal position.
