Laque differences

 

Color: Lapis blue

 

Trim: Cap band

 

Thin band (earliest)

Notice that the band is so thin that nothing could be inscribed on it.  All inscriptions are on the cap that has laque applied.

Wide band

  

The use of dark red paint to sign on the red laque material makes it very difficult to see the Chinese characters.  I have added the identical image but with the contrast toned down in order to reveal the characters.
