Metal hedgehog figurine

Looks like Sheffield silver from 1987.
Obviously filled with something else though!

Would look lovely cleaned up.....

I think the current colour is how it has been designed. These modern silver items often come in great shapes. You have a lot of information on the outside to tell you who designed it, who cast it and what year. The filled bit is just to warn those who melt such things for scrap that the weight is not all silver.
