I do harbor some doubts as these signs usually were not brought down as intact as this piece. As I also mentioned, better close up detailed pictures of the mounting holes would tell a lot.

I've read somewhere recently that Wilhelm Saris is working on a book about signs during the TR period.
I would honestly send this one back for a refund if you possibly can. I don't like it at all. There is simply no age to it. It is the same as the repros I have seen.
