Can't see a lot of detail in the pics, but Vulcan barrels would make it an early VH if that 1899 date is correct. Does the barrel SN match the frame and the trigger guard? That butt stock is spectacular for a VH (looks way too good), so may not be original to that gun. Looks like butt lumber does not match the fore end. Straight grip and super wood make it a very nice shooter even if stock is not original. 12 gauge, 2 frame, 30" is about the most common configuration for a VH, but straight stock is pretty scarce. Ejectors would make it a VHE. Someone with the Parker Serialization book can check for original configuration. Does the TG have a SN engraved on the tang? Should be a long tang unless converted from PG. Looks like a proud screw on the tang. I think Parkers had the SN stamped into the wood under the tang. Gun probably came from the factory with a spurred, hard plastic butt plate.
