IMO the Blue Book is the most over-rated reference book out there.
I buy guns all over the country and don't ever understand their prices.
Auction prices ?
The last 1886 .33WCF I had, in a take down model, 60% gun, was traded to a dealer that has about 6 tables at every show. He toted it around for about 2 years
Before it was gone.
Last price I noted on it was $1200.00.
A special feature gun takes a lot of time and effort to evaluate.
Don't ever let emotion enter the evaluation.
Don't pay for condition that is NOT there.
