I purchased a 1950s-60s vintage Duo-Art electric/pump console player.
It plays perfectly with electric with newer rolls, but the one older
roll I played was ripped on rewind.

Is it best to play old rolls with the manual pump?  I did notice that
my older rolls which were only played on a pump player seemed to be
tightly rolled.  Should they be loose?   Would appreciate any
suggestions.  I don't want to ruin any old rolls.
