Those old Prestolite batteries are pretty neat. On a related note I'm always hoping to find more sets of the original style mower blades for the 38" and 42" cast end decks that are in new or very good condition...the wing tips were different than more recent replacements and the cutting edge wasn't angled off like the newer ones. These are very hard to find now, but I did manage to buy a few from Lew P a couple years ago.
