Hello,
This vase design can be found in the Brockwitz catalogues from 1915 to 1931. It has the number 09233/24 & 09233/31 (1915 cat.) or 9233/24 (1931 cat.). This would indicate it was 24 or 31 cm. in height. If yours is 14 cm. this means that another size not shown in the catalogues was made. It was also iridised in the marigold colour and was named by carnival glass collectors, before catalogues became available, as Footed Prism Panels.
I hope this information is what you are after.
Neil
