Hi,
The jacket is called a frock coat and I believe at this point anyway they were peculiar to the guards regiments.
They were private purchase and did differ slightly. They were made of dark blue cloth with black frogging and embroidery,,,no fur at this point.
There are lots of pictures of guards officers taken by roger fenton wearing this garment.
I thought it looked cool so got moz to sculpt it,,,bit different than red !!!
Seriously good painting Ernesto
