How old are the katar types?

[Jens Nordlunde]

From 1650 to 1800 the Danish kings had their own private museum, containing many different things - katars as well.

From 1648 to 1845 Denmark had a trading post called Tranquebar on the south east coast of India, and many Indian items were shipped home to the royal Danish museum. Amongst the things were also the five katars shown on the picture.
The ones who collected the items did not write from where in India the different items came, nor did they write in which year they had been collected, or if they were new or used at the time, but we do know something else, we know when the katars entered the collection. They entered the colelction in the end of the 17th century.
