Fair value is 3-3.5 K from what I see selling. Guns listed on the Internet do not sell if you are seeing them listed and relisted for months or even years. Common misconception about fair value is that asking/listing price is the average selling price . With the extra wood I would be looking for about 8k for the pair. If you are selling them a dealer will tell you the extra trigger decreases value and when he has the same guns for sale he will tell you they are rare with two triggers and ask extra .

The extra wood is a lot of work for the average buyer. He may pay someone else to do the work but that may set him back 3k per gun to finish the restocking
