Unusual trade badge

[Garth Thompson]

I recently aquired this bullion on wool trade badge which I can't place to the trade it denotes or the period it comes from. As you can notice from the picture it is substancially larger than the commonly observed badges. It is 3 1/2" x 4". Any thoughts much appreciated.

Colonial, from the style of lettering & backing colour of what is presumably a dress quality item, Victorian / Edwardian from the size?
