Hi,
I hope that someone can help. I have just discovered this photo of an ancestor from about 1855.
I believe the uniform is from the Crimean war era. The badge isn't very clear but there are some details visible which should help identify the regiment.
Google image searching for several days have revealed plenty of shako badges which are similar, but not identical.
The most likely locations of regiments are:
Dorset (or surrounding counties).
Middlesex.
Kent.
Any clues much appreciated,
James
