For the first physical convention since the Pandemic I was pleased to present an exhibit using more data compiled from The Register.
"Odd Men" focuses on officers and soldiers from the regular British cavalry who served in the war but not with their parent regiment. Very often they earned different clasps making those medals prized by collectors. I analysed the clasp entitlements for the regiments, those that deployed and those that didn't to produce a spreadsheet allowing "odd men" to be easily spotted.here.
The "Odd Men" Identifier - a spreadsheet of regiments, clasp entitlements and more is here.
