Yes, I do have nickel D/B's. 2 1/2" 38, 4" 38, 6" 38, 4" .22, 6" .22, and 4" "Electroless Nickel" and all of the preceding in Blue plus 2 1/2" .22. All are NIB. Paid $89.50 each for 2 - 2 1/2" blue .22's from J and G in 1973, I believe that configuration was discontinued about then due to poor sales and J and G was discounting them at that price to FFL holders. Will try to get some good pictures of all of them in the next few days...
