GURPS Steampunk
Curtis Handsaker (Z09SS) converted many 3e weapons into 4e which were posted on the RPG net wiki. The weapon pages have been reformatted to make them a little easier to use though because they are so long they are given their own pages as on RPG net wiki. This overlaps with Weapons of GURPS Old West (1830 to 1917).
