By contrast, on enlistment, he looks like this.
Finding differences may seem academic at first, but it was a distinction recognized by the soldiers themselves. It simply wouldn't be right to put Oliver Pattern equipment on a five button tunic. For this reason I researched several examples of the seven button tunic in Ottawa finding that the only constant element was....seven buttons, and mostly a stand up collar.
This topic has been covered in another blog so I won't repeat myself here. Check this link:
The point I wish to emphasize is not so much the details of the seven button tunic, or even the reproduction by What Price Glory, but the difficulty in creating a single representation at a time when there was no absolute standard. Here, then, a reproduction becomes an impression, like a sketch. It is the essence, distilled, and yes, there are two more buttons beneath the Oliver ammo pouch in this photo.
What Price Glory is now reproducing these tunics in sizes for the modern man. Don't be scared off re-tailoring! They did that in the trenches too.
