same was shown in the thread "HJ in white", about a month ago, on November 20th by Lauri.
His shown badge included a white cloth "flag" with Japanese characters. Have a look there!
Thats the identical one as was shown here. (Wonder why Lauri sold it?) Looks like it is in need of a clean. (that looks very much like nicotine stains)You could take a cotton bud, dip it in window cleaner and gently clean the enamel surface. I dont like tampering with the Patina of any item, but Glass enamel can not build up any patina so to speak, so gently cleaning the surface with a normal window cleaner wont do any damage, and it will look much better
Its a nice item indeed.
