Late Qing tea cup (?)

[Bok]

Dear all,

Another market find. After recent doubtful acquisitions, I am carefully a bit more optimistic with this one.
From other researches I have seen identical antique cups (unverified), which were marked as late Qing.

Anyone has more insight, doubts?

Thanks!

Late Qing should be no problem, in my opinion.
