How do you do this??

An old razor has come into my possession, made by Cadman & Sons, Sheffiled, England & branded Bengal. It has had a fair bit of use but basically in good condition.

What I would like to know is how do you remove the blade from the scales. I would believe that the pin could be tapped out with punch, providing the whole razor was well supported. I have had a tentative go at it, albiet nervously.

Even though the razor has been well used the blade is a little stiff to move out of the scales, I would believe there is a small amount of rust in there that I would like to clean out.

Any assistance on this would be greatly appreciated
