It is highly likely that those radios are actually 20KHz bandwidth, not 25. You'd have to be looking at radios well over 30 years old to see 25 KHz bandwidth. If the FCC Type Acceptance shows an emission code that is 16Kxxxxxx, it is 20KHz. Given the fuzzy response from the FCC, you may consider legacy 20KHz radios to be very usable in GMRS. I do. The narrowbanding effort that culminated on the the deadline of 1/1/13 brought most of Part 90 down to 12.5KHz, forcing a lot of agencies to remove their older 20KHz only radios from service which is why you see so many of them for sale on auction sites.
