Brass handle

I admit, I love Colonial's SE razors. As you may have noticed from my SOTD entries, it's what I use almost exclusively. However, I have trouble with the smooth handle that came with my brass General. It doesn't actually slip in my fingers but doesn't offer much purchase and it makes it a little difficult to control the razor.

Does anyone know a source for an alternative (and affordable) brass handle with better grip or some sort of knurling? If you have one you're looking to part with, please let me know. Preferably around 85mm long.

Here's a picture of the razor and handle:
