This is Old Vienna Keiserliche Fabrik (Imperial factory). Blue under glaze beehive (Bindenschild) and years 1816 and 1824, not uncommon for white porcelain to be produced within the span of several years, stored and then decorated for the market (even cups and saucers made in Vienna have different impressed years. What is seen in one picture is NOT a damage but hairline crack due to firing process where the handle is attached to the body of the piece. Normal finding even in small objects like salt cellars and let alone in this huge tureen. Letter A with number ``16 indicates the gilder Karl Radimacher who worked with Vienna porcelain factory from 1819 to 1851. Amazing gilt decorations on massive example which weighs about 12 pounds by itself. This is 16" tall when lidded with the base being about 14 1/2" diameter. The urn itself is about 13" handle to handle and 10" diameter across the bowl. I can see there are shadows of sparsely strewn flowers which are no longer visible. There is the one hairline in the rim as photographed that is in the making and nothing else to note. I believe the feet to the base have been re-done or reinforced possibly, but hard for me to tell for certain. This is a large and rare piece of extremely fine porcelain. Both pieces have beehive marks and 3 digit numbers like 824, and 816? There are a few other marks impressed and script. A fantastic piece for display or use even.
