By a company called LWF...?

Bait doesn't taste too good.

No.

Are we looking at an aircraft built prior to 1917?

To be precise, 1916.

Well, I've got some serious googling to do as I have the first American bomber listed as the Martin GMB of 1918?

Google was my friend.......

Rosebud or Aerofiles? Or neither?

From Rosebud.

I've just discovered it's also in Aerofiles.

I have to go now, I'll leave the green light on.

Back in fifty minutes.

Well, he's not my Fokker Friendship, but he did help me find No.16, the Andermat Biplane...

Search AEROFILES.COM: biplane bomber prototype

Looking at the chap in the centre, French?

I've been playing with image a bit, and that uniform looks like a very old version of the British Post Office.

So is it by any chance British?

Yes, British and he does work for the Post Office.
This is a rehearsal at Hendon for the 1911 Coronation mail service that was to start a few days later.

That's a big clue, but Google and I are having an argument. :\

Got this so far:

Well try this then...according to Peter Lewis this aircraft was the first to fly cargo by air in Britain..

...a box of Osram lamps...
