Actually the legs as shown are correct for that style of stove. Don't know why, as they really seem out of place, but if you check out those old stoves they often had that sort of leg assembly. One thing is for sure, those stoves were heavy and those legs although spindly, could hold the weight.
Back in 1991 I built a home for my mom and she insisted on one of those stoves, although a new one, and while very lovely, quite plain by comparison. It was about 30" round by 7' tall, and was completely covered by white tile made specifically for the stove. Mom paid about $16,000 for it, and it required a foundation that went 3' into the basement floor, followed by a block foundation that went to the first floor. The factory installer took 3 days to assemble it.
If you look on the Internet, there are sellers in Germany which specialize in selling these old stoves. Even ugly ones come quite dearly ($$$).
About the eBay comment on it coming from the Schoenbrunn Palace in Vienna. My parents scoured Europe for antiques and did indeed purchase some items from the Palace. Apparently they had some sort of a store for marketing what was not wanted. This would have been just after WWII. Back then much of Europe was for sale to bring badly needed money into their economy. One of the problems with such sales is a matter of scale. Few USA homes are designed for some of these antiques, weight and height being a problem.
