Certainly not a D, it is a G grade receiver and it looks to me to have Vulcan barrels and a V or P grade stock given the checkering and shield.
The Serialization Book says the serial number should be a V grade, capped p/g, 28" bbls 16ga with ejectors. No mention of BTFE or SST. This is in the Remington era and odd things did happen then, I don't think it's even close to a 30K gun but as far as it's configuration, never say never.
