Thank you Rocketman. I sent you photos via your email. You will notice the missing firing pin and nut that holds it in. I look forward to hearing from you on your opinion of this gun. Would you figure the CC and OQ and then deduct the cost of replacement of the firing pin assembly?
Got the photos. E. C. Green is ranked as BV3 by the market. This has nothing to do with Original Quality, just the value added by his (maker's) name. I agree that this is a "best work gun." The market would grade it as OQ5 - best work BLE and hammer guns. "Shootable but needs some repairs and refinishing," seems to me to describe it; CC6. I'm assuming the barrels are good and/or will clean up, the gun is reasonably on face, and there are no wood issues beyond finish.
So, BV3-OQ5-CC6 = $1,336. I'd expect the firing pin system to cost $200 - $400 --- will take a little lathe time.
If you are feeling stingey - $800, generous - $1,500, and on the button - $1,000. You could legitimately give those prices a small ding for 10 gauge.
How does that stack up with your thinking?
