It's kinda charming when some old-school address or phone number, that perhaps few have used in a long time, still works.

Circa 2010, I bought a vintage Concept2 Model B rowing machine, made in the 1980s, and wanted to fix it up. The paper order form I found for parts was similar to those tiny order forms at the bottom of an ad in an old comic book, where you'd handwrite your return address, and it told you the address to mail it to, with your payment.

Somehow, not only did this address still reach them, but they were set up to fulfill parts orders this way, they actually had the parts for this decades-old model, and sent me the parts (for a pittance), and they tossed in a free service manual.

I already loved the product (from using it at gyms), and now I loved the company.

I wonder what percentage of 25 year-old URLs still work.
