Yes can go with 1845, but still prior to 1856. The image you have shown is a Drummers tunic of the Scots Fusilier Guards. Note the buttons on the original post are in pairs the Garter Star can be seen.( Coldstream Guards. The Front & rear pictures you have posted the Buttons are in three's so Scots Fusilier Guards. As its from the Borodino Museum I would guess it is in the Crimea War Section?
