For $550 each, a good price. I'd consider buying one and "losing" that stock until I got a more accurate date from Remington.New standard 11-87 stocks, both synthetic and wood, are neither scarce nor all that expensive. It's a silly law, but let's not be silly about breaking it.
These would probably make as good a 3 gun shotgun as the new 1100 Competition Master written of elsewhere here for a couple hundred less. And a nice House Shotgun also.
Note, these may not cycle lighter loads well.
HTH...
