Does it all match up?

Hello, my SRP friends! :)

I've been eyeing this DE for a bit of time, mostly because I'm a re-enactor who is in need of a good ww1 german shaver. I'd like a DE to go along with my straight, but am wondering if this is period-specific? I need something 1918 or earlier, from the German Empire.

Thanks for the advice and any information!

It's certainly "of the period" but whether or not it's 1918 or earlier is hard to tell. It's a copy of a Gillette "Old Type" that ran until late 1920's.
