#2325, "$6.50 power handle for Shimano round baitcasting reels"
I just bought a $6.50 power handle made for Daiwa Firewolf 27H to fit my new Shimano Corvalus 301(same size as Calcutta & Cardiff). You'll need to file the hole to fit but it works great, even the little screw thread for the nut cover fit. The metal is thicker but a little shorter than the Shimano stock live bait handle. It's not the greatest handle and I wish the shape of the handle is more cylindrical but for $6.50, I can't ask for too much. Here is a picture of the handle:
