The Prince Henry in silver in picture 1 and gold in picture 2 is getting hard to find now. In picture 3 it is on a pen & pencil holder (desk-tidy) and picture 4 shows it mounted on a plain trinket box.
A number of the painted versions have been 'found' with maroon seats claiming to be like the rare red version but these are considered to have been swapped from the plated model.
