Tsuba Mune?

[Tavroch]

I just bought these two tsuba:

 

 

This was the description:

 

Left tsuba:

Mei: Mune ?

7.02 cm x 6.62 cm

Middle Edo period.

Tree and 2 Chinese men are engraved with gold and copper iroe.

 

Right tsuba:

Mei: mumei

7.26 cm x 6.70 cm

Middle Edo period.

Man with sword is engraved with gold and silver and copper iroe.

 

The right one drew my attention. I suppose this is Shoki?

Any chance this can be a depiction of a Dutch or Portugese tourist?

Any chance these tsuba were made by the same artist?

I think the style, especially of the back sides, is rather similar.

Here's the mei on the left one:

 

Can anybody read what it says? "Mune" as in the description?

Furthermore: I read a recently reanimated thread about lacquer on tsuba: these have both got lacquer on them:

 

Especially visible in the deeper parts. It is quite hard: a wooden toothpick or a fingernail won't leave any mark.

The lacquer covers the copper inlay near the nakago ana of the left tsuba so it must be applied later.

Here's a detail of the lacquer in the holes of the left tsuba:

 

Any ideas on when this lacquer was applied?

I welcome any further remarks or comments.
