I have an old razor that has a set of red-horn scales....
They look as though they were 'blond' scales that were dyed. Unfortunately, that is all I can tell you about them! BUT, it can be done.....
If you want I can post a picture of the razor.
OR, you can wait until I post it in the 'for sale' area or on eBay ;)
(I've been meaning to do that, but like so many other things, something came up)
