The issue with the pictures is that they are probably too large. You would probably need to resize them before posting them.
I have had some planes where the japanning was pretty well gone. All of my planes are users. It is a matter of personal preference since it is just an appearance issue and other folks paint, paint with epoxy, and powder coat them. I choose to just give the non-mechanical surfaces a coat of shellac. It doesn’t male them look like new but helps prevent further rusting, gives them a little shine and can easily be reversed by future owners.
