Have this fantastic T & co brooch!

I have this fantastic piece of brooch, marked with a passant lion, an anchor an an gothic (?) m and the t & co mark.

It looks like an old swedish costume jewelry and its thin and very very light. Excellent condition accept some small buckles.

In urgent need of help getting this one valued, thanks a lot meanwhile!

Here is a oicture of it:http://tinypic.com/view.php?pic=2u7t91g&s=7
