Hi DJB, My first thoughts were a American Western sheriff badge design and as you say very unusual so I had to have a quick look. Easton, Huntingdon appears to be a small hamlet with a local church of St Peters - between Kettering and Cambridge. Albert Brown gives seven likely contenders and we know he was Second contingent from his return date (assuming he did not stay out there from 1st contingent). The second contingent were recruited geographically and sent to Aldershot where they were assigned to the next company which was being formed. So the companies which left Aldershot were not related to the traditional recruiting areas of their men's home county. There was some form of preference but as all Yeomanry were going through Aldershot Garrison the IY were fudged into the next Company being formed and sent out on the next available ship. Little training was given to the IY in Britain as Kitchener ordered that this would happen once deployed. 2nd Contingent started to form on 24th January 1901 and by Middle of February had enlisted 16, 400 men. Once arrived they didn't even enjoy the luxury of Mateland Camp and 6 weeks acclimatisation which the 1st contingent were afforded. As I understand it there was a brief handover and then they were quickly transported inland. So many had not had a chance to fire their guns let alone zero the sights?
Brown, A. 29500, Private 100th Coy., 5th Bn. I.Y. (Northumberland)
Brown, A. 22520, Trooper 4th Coy., 1st Bn. I.Y. (Glamorganshire)
Brown, A.J. 15936, Private Imperial Yeomanry - I would need to look at service papers
Brown, Albert 3472, Private 12th Coy., 3rd Bn. I.Y. (South Nottingham)
Brown, Albert 24718, Private M.G. Section, 11th Bn. I.Y.
Brown, Albert 32010, Trooper 12th Coy., 3rd Bn. I.Y. (South Nottingham)
Brown, Albert Ernest 2477, L/Corporal 48th Coy., 7th Bn. I.Y. (North Somerset)
I'm sure your way ahead of us but have you proved which he was yet? I respect you likely have searched the service papers and would be pleased to know more about Albert Brown and who he served with
