As the ER 1914 has a smaller thread on the head/handle than the 1912, 1924 and Streamline, I've been looking for a way to attach a modern S/S handle.
After using my Standard DE, I had sudden eureka moment when I remembered the grub screw with the double thread.
The the larger thread is M5 and fits the handle as well as other modern handles. The smaller thread that fits into the Standard head is actually smaller than the 1914 thread.
I found a nut that fits the smaller grub screw thread.
et voilà .
My next shave
I now need to find the size of the smaller thread and a source of similar grub screws.
