Restore? or Leave alone? When to meddle in the vintage stew

So when is it appropriate to leave a vintage pad alone simply because it’s vintage? And when is it appropriate to repair a vintage pad to make it playable again?
This is definitely a case-by-case situation. But I’d offer my own personal parameters as a starting point for discussion.

1. I’d consider repairing an old pad if:

— it looks like dozens of other pads of similar design;
—there’s no identifying logo, decal, badge or distinctive design element to set it apart;
— it’s identifiable as one of thousands manufactured;
— you didn’t pay much for it;
— it meets at least three of the above and someone would enjoy playing it.

2. I’d leave the pad alone if:

— it has a logo, badge or distinctive design element that sets it apart;
— it’s a long shot but you want to research it further;
— you paid more for it;
— repairing or otherwise altering it would diminish its historical and financial (because let’s be real) value;
— there’s nothing else like it in your collection;
— it’s a double you might use to trade later for something else (I try not to keep much on hand for this purpose as it clouds my reasons for collecting to begin with).

Below is an example of a pad I’ve decided to make playable again. It’s just like the three other pads I have that are in better shape and have intact decals or badges; it’s condition was poor/unplayable but repair would make it useful to someone; and it wouldn’t end up in a landfill.

I’ve removed the original rubber disc, which will serve as a pattern for its bouncier replacement after I clean the old glue out of the recessed area.
I covered the underside with repurposed gaming pad, rubber side showing as a non-skid surface.
(I’ll save the old disc as another non-skid surface for a future repair.)
And when it’s done, I’ll have a nice no-name practice pad to keep or re-home.
