Hi Frank, It's nice to know someone else prefers the elegance of hinged stone guards. I have advertised looking for these for three years without success. On my KN, I made them and I thought I might be able to avoid the effort on my current project. Perhaps you might know someone who would produce a batch?? Best Chris
I just been in the attic and found a pair of original factory stone guards but they are for a 140 Lucas size lamps. Just a note they are numbered as a pair. They are just as your image shows with twin rims.
