Victorian Art Glass Vase with bird

This little piece was advertised in Excellent condition but it was hard to tell as the pictures were out of focus. I could see that the feet were perfect, they are normally the first thing to get damaged, even so it does wobble a bit. When it arrived I immediately noticed what looks like a sliver out of the glass just by the tail and a very rough repair but the elderly owner says it was always like this and the raised piece will not come off. After looking very carefully with a magnifying glass you can see that the repair has the twig painted on it. You would think that if a piece had damage they would dispose of it but it seems not to be the case. The guy did do me a partial refund anyway. 160mm high.
