Im trying to identify the person in this portrait and the starting point is to find out which regiment he was in. Ive done as much research as I can online but there is so much detail I've got confused. This is what Ive found out so far. I think it has been painted in about 1870. His forage cap is that of a Lancer's officer (but not of the 16th as they wore red ones?). His coat is an officers patrol jacket and could be of Queens Dragoon Guards?
Also whats the difference between a Lancer and a Hussar. Im happy to be corrected on anything!
Thank you for your help.
