Small Blue clear cut glass vase

I have recently purchased this small cut glass vase, i have tried to find a similar one. i have found some very similar for sale and listed as a blue and clear cut bohemian vase. Any help gratefully accepted. there are 4 or five very small letter on the underside in stamp type form, they appear to read TCUO although the last 2 digits are hard to make out and Too small to photograph.

Screaming Bohemian...
