I say old pump guts in newer 50-60 pumps dump the guts.Nothing ascetic about the internals of a newer style pump .The old boy's however are mechanically a work of art and pleasing to the eye to boot.Just like everything else that has some age to it.
You sound like my Father when I wanted to buy a 60's Muscle car.He wanted me to buy a Model T & said no one wants a hot rod.
Today he apologizes everytime a Mecum,R&S or Barrett Jackson type auction runs.
