I believe they made these in 357 mag, 41 mag, 44 mag, and 45 Colt. I think they made about 250 of the 41 mag and one other caliber, and 500 of the other two calibers. I saw a matched serial number set of all four selling for $3200 several years ago. Wish I had the money, but then again, I'd shoot them all and take the value down. ;D
I bought one of these sets when they came out, back when things weren't so tight. I have all 4 in serial number 13 and am shocked to see them going so high. I had an extra in the 41 magnum, but sold it to a buddy cause he wanted it so bad. Wish I had it back.
