I really need some help with this one. :\
I don't know much about the Red coats or their ranking system; nor do I know much about the man in the picture.
All I can tell you is that:
The man is from England (Yorkshire) and the photo was most likely taken after 1890.
Is there any additional information you can give me about this image or if any of the information I have given you (eg. the year) seems wrong?
