It will more than likely work. The thing you need to look at is if the "sprocket" hole ID will match the shaft on your mill. Remove the handle and measure it.
It's no big deal to open it up or make a sleeve if it doesn't mount right up.
Those power feed hubs/connectors are a 17mm inside diameter. Just to make checking easy.
That one looks like it mounts on the right side mine mounts on the left. I'm right handed so I prefer to manually crank from the right. I didn't buy mine from Shars.
