Well it's unsusal to me, maybe not to someone who is experienced! I have a stamp with the letter A and possibly I or T on the back. Hopefully you can see in the images. Does anyone know what it is? I haven't seen one before.
The A I think can be seen fairly easily in the photo, the I or T is to the RH side on the top RH corner but not so easy to see in the image.
