I haven’t got the company name, but a friend of mine buys his shoes by mail from a New Zealand company. After 5 years, a seam failed. He thought he’d got fair wear out of them and needed a new pair. When he called, they apologized and sent him a replacement pair.
My local roofer offered a lifetime guarantee on my roof replacement. Three years later, he went out of business. Fortunately, the guarantee is also honored by the manufacturer but that applies to material only.
My mother-in-law paid way too much for a set of carving knives at a state fair booth many years back. When I told her she got ripped off, she replied, “The price is worth it, because it comes with a lifetime guarantee!”.
RadioShack branded vacuum tubes came with a lifetime guarantee. Until around 1970 the replacement tubes also came with a lifetime warranty but sometime after that they stopped selling the RadioShack brand tubes and the replacement tubes had no guarantee.
I remember Craftsman hand tools (wrenches, sockets, etc.) had a lifetime guarantee. And they honored it, even without a receipt. Not sure if that still applies, since Sears is no longer around.
Sears sold off the Craftsman brand to Stanley Black & Decker in 2017, but it looks like they are still honoring the warranty (even with some strings attached). As per Wikipedia:
In the last few years, I’ve taken Craftsman tools back to Lowes and Ace Hardware. Generally it’s not too much of a headache but a few times I’ve run into issues where the store doesn’t stock the same/similar item or the manager either doesn’t know they’re supposed to be exchanging it or doesn’t want to. One of the times the manager gave me a phone number and told me to call them and I couldn’t get him to understand I had just been on the phone with those people (same number I already had) and they told me to come here, to this specific store.
In any case, I’ve slowly started migrating from Craftsman to Kobalt. Sure, Lowes might go out of business too, but I find it easier dealing with these types of lifetime warranties when there’s only one store that sells the stuff so you don’t have to worry about keeping receipts to prove where you bought it.
Besides, I kinda treat the lifetime warranties with a grain of salt. It’s nice to walk a 50 year old Craftsman ratchet into a Sears and walk out with a brand new (and sometimes expensive) one for free, but it’s not the end of the world if I can’t.
And I apologize for the Craftsman hijack, but can’t help it. 
On a related note, I bought hundreds of Craftsman hand tools in the 1980s and 1990s. I still have them, and they all say “Made in the USA” on them. If I broke one, am I correct in assuming the replacement would be made in China? And if so, would it be the same quality as my Made-in-the-USA one?
The random tool I looked at (a ratchet on the Lowes website) appears to be made in China.
Apparently foreign components assembled in the U.S.

One of my relatives once was digging in their garden and found an ancient, rusted hammerhead, with an engraved “Craftsman” just barely legible on it. Sears still honored the guarantee, and gave them a new hammer.
Though that was back when Sears itself still existed.
There’s a roofing company in St. Louis that dates to 1929 and another that was started in 1947. There are probably some others, but those two demonstrate it’s possible.
For a hole in your roof … or a whole new roof!
I waited on the owner several times, twice they were in the company of #6 “Stan the Man”.
