My John Connor Rebuild Anglo has the usual round hole on either metal end-plate for the maker's name but they are both blank and just empty holes. Is this usual and/or a problem? I don't want to mess with this and cover them (by making a label) unless it's thought necessary. However, the maker's name doesn't appear anywhere that I can find and that may mean in years to come, when it gets passed on, no-one may remember who made it.
