I tried some photoshopping on Ericlaude's images; though the colors are not correct, more details have become visible, I hope.
Telling from the both general shape and construction and the bolts/screws or rivets used, I should not date it before the 19th c. Thus this might be one of the numerous Historismus (Victorian) copies, including that certain amount of both style mingling and fantasy characteristic of that period), of Renaissance originals like the one in Venice.
As the iron surfaces clearly show significant differences in rust and pitting I assume that some older and not belonging parts were associated.
