Thank you for your post on my Ruger firearm. Mine is the New Model Super Blackhawk 44 mag with the 10 1/2 inch barrel. The SN is 83-915xx. I looked at the wrong model in the Blue Book. However, even if mine were the older model it would not be worth the $1,900 as it shows some wear as it has been shot. It does not have the original grips on it. It has Pachymar rubber grips. For the life of me I cannot find the factory grips. I know that I did not throw them away, I simply cannot find them. The revolver has some minor scratches on the bluing, not bad, but honest wear and tear on a using gun. From what I have described to you would the value be the $500.00 or so. I know that it is very hard to come up with a value without seeing it in hand. Just looking for a ball park figure.
