Cornwall In The First World War

During this month, each weekday I'm posting a different image showing aspects of Cornwall's First World War.

Today I've selected a 'mystery photo'. It was taken in the Helston area, possibly during 1914. Beyond that, we know nothing about what's going on. A couple of points: firstly the soldiers' trousers are of darker material than their jackets, which is unusual. Secondly their cap badges are round, so we can exclude them being Duke of Cornwall's Light Infantry. 

They may be members of Cornwall's Volunteer Training Corps, but these part-time soldiers usually wore identifying armbands displaying the initials GR: no armbands here. It's more likely they're part of the later Volunteer Force, but in that case the photo's date would be at least summer 1916. 

Any thoughts or information on these gentlemen would be most appreciated.

My book, 'Cornwall In The First World War', is published by Truran. With 112 pages and 100 images, you'll find it in bookshops across the Duchy. It's also available through Amazon: http://amzn.to/19JbtZm
