What levers were the hoods for? There were a couple of distinctly different body shapes as can be seen by the different contours at the lever arm openings of these hoods in the eBay photo:



Not a big deal, except some hoods will fit very well on the levers, and others will not. This is true of replacement hoods by AME or Dia-Compe too. The Darker color hoods in the photo are definitely an older style and those would also be better if your levers happen to have built in cable adjuster "stacks".

The lighter colored hoods are more modern, will nest against a handlebar to make a less abrupt transition to offer a more comfortable fit. The older ones are generally thicker gum rubber and more cushioned. They are also far more difficult to find and more costly. Yours appear to date from a transitional period, perhaps mid to late 1970s? And still have the older style of logo, thicker gum rubber, but also a more modern Campagnolo-like shape.

Just make sure you notice the difference in the shape of any replacement hoods you consider to best suit your needs.
