I have come across this minute mark on my box,recently arrived ,on the side where the lid goes on.
Images not that clear,very difficult to get good image,a friend took these through lenses of very powerful microscope.
the best I can do.
Is this just another Ratzersdorfer mark,or something else? as it has his mark on base strange to have mark here,unless this mark has something to do with the lid (not marked)
I have done rough sketch of mark ,not sure if the small marks are letters,or crosses?
I have not seen this mark so far if it is his mark. Has anyone seen this mark before?
Regards Guido.
