I believe this fill was incorrectly renamed. Gun in the photograph has a provenance as a howitzer not a gun. I belive this eduit should be undone. The name was changed from File:CW Arty 24 Pound Howitzer rear.jpg to File:CW Arty 24 Pound Field Gun rear.jpg. The only comment was "not a Howitzer". I saw no attempt to discuss this change on the image talk page or in the article where the image was used. There was no reference provided for the edit?
The tube in the picture is actually discussed in some detail at the following reference and is clearly described as a howitzer. [1]. The following reference discusses the same guns as being howitzers. [2] and [3]
Artillerymen have often argued over exactly what seperates a howitzer from a gun, but this particular tube seems to be well dcoumented as a howitzer.--Aleutian06 (talk) 14:24, 18 December 2015 (UTC)
