Im getting a 25c for Christmas and wanted to try the Muhle.....will the 25c handle work with this? http://www.royalshave.com/p/410-020-00/muhle-open-comb-replacement-head
Yes, Merker, Muhle, and Edwin Jagger and most other 3 piece razor handles have the same size threads and can be interchanged with other razor heads.
No problem with the Murker handles. My Murker 33C handle fits my R41 and my R89 with no issues and the handle works just fine. The 33C handle is just a little shorter than the 25C handle. Pic of R41 with the Murker 33C handle. Happy Shave On To All, Bill G
