Small pottery vase - flat black w/ enameled leaves.

I have this small vase that I am assuming is possibly European based on the incised mark on the bottom. Does anyone recognize the style or help me with a direction to go?
It is 3 7/8" tall & is done in a flat black with enameled leaves. It has the number 7646 on the foot with an "I" in the center.



Thanks for any & all advice or opinions!!!

 

The base makes me think Austria - Teplitz style
Somewhere around 1900

Wonder if it was part of a wash set
Not a vase, but a toothbrush

For comparison - look at the thick rim, glazed inside with number in center.

Hi Pat!!
I guess it could possibly be part of a wash set, but most of the toothbrush holders I have seen are taller.
Thanks for the lead & suggestion. I'll do some poking around in that direction.

Hi Peggy -
You're right 3 7/8" is on the short side.
Until I pull out the ruler and actually see the measurement it doesn't always compute. And I didn't do that this morning. Sorry.

 

Hi Pat.

No problem at all!!!
