He died at Worthing on january 17th, 1919, aged 85.

The carte-de-visite is hand marked "july 1880". He's wearing the badges of rank of colonel on his collar - those will be shifted to the shoulder boards that very year. This photo gives a clear view of the cuff embroideries (for Lieutenant-Colonels and Colonels) and the old "Light Dragoons" pouch belt pattern.
