Safety Razor Hardware Sources? Anyone have a lead for me?

I have been making Silvertip Badger Brushes and Razor Handles for a while now but…. customers are asking me on a regular basis if I can do “Safety Razor” handles. Now I have one source for the hardware and the quality is top notch. www.thegoldennib.com But, this set of hardware is for the top of the razor only and needs to be screwed and epoxied into the handle.

Where the problem lies is that most customers was a razor handle that has a metal endcap, like the usual Gillette handle kits. Does anyone know where these kind of hardware kits can be found? I would prefer one that uses the 7mm brass tube and assembles like a pen kit. (Like the Gillette version)
