Has anyone ever seen this (Qianlong?) red seal mark before?

On the base of a cup; two characters only. I have struggled to find one identical via google search.

My knowledge of seal script is limited but I believe it says 'Qian Long'

Sorry, but unable to provide clearer pictures.

Yes...but this does not mean the item is of that period.

Yes. To my knowledge most red Qianlong seals are later and favoured by fakes. Is this one dateable; is there a possibility it is contemporary with his reign?

It's on a famille rose cup depicting the eight buddhist treasures. Will post some more pics later this week.
