Reasonable price for DH 12ga with following specs

[Tom Eldridge]

I'm new to the Parker community and was hoping you all could provide some assistance in valuing a SxS. It is a 12ga DH from 1896. It has been re-finished.

Specs:

1 1/2" frame
2-5/8" chambers
Skeleton buttstock
~>90% finish on Damascus barrels (comes with 28" and 30" barrel sets)
Factory case colors mostly silvered over (take a look at the attached photos)
No pitting in bores
Nice re-finish on stock and forends, no major nicks/dings in the wood

My best estimate is between $5,000-$6,000, but I am concerned about the lack of quality factory case colors.

The latest Blue Book estimate I have access to is almost 20 years old, so I'm guessing that significantly under estimates the current value.

Any thoughts on this?
