Can you identify this WW1 gun please?

I am doing some family history research for some distant relatives by marriage. There is a fantastic treasure trove of 100s of photos from 1895 onwards!
This one caught my eye. There is nothing written on the back unfortunately but it is a large high quality photo.

Could be one of these possibly

It looks like British uniforms on the soldiers so I would start from here. You could try google image search but that was the closest match I could find

that same photo is on Wikipedia as well with this caption

'The Battle of the Somme, July-november 1916 Ben Tillett (trade unionist and founding member of the Labour Party) Visits a howitzer, Martinsart, autumn, 1916.'

It's not a Luger...

I don’t know what it is but I like the sound it makes
