I think as Jim says, The short one is a lot stronger, and does the job of "destabalising" the pin from its working position (from there on in normal usage) it would be an easy job to chase out with the long one. fifty or sixty years of rust was never in the equation.
I do think Jim's short punch is a little on the short side (shorter than mine as I recall) (I haven't seen it for a while though)
