French 37mm Projectile Mark

On another thread I discussed a 37 - 85 French projectile that I was rebuilding. While cleaning the rust and grime I noticed several stampings on the projectile body. A letter R, an ordnance bomb, and the symbol shown below. It’s about 1/8" in height.

Anybody seen this before? What is it?


OK, 59 of you have looked at this and do you mean to tell me that not one of you know what it is??

It is 51 degrees, the wind is blowing and it is raining. Three things that will make any AZ resident go Postal. The rain was fun to look at for a while, but it’s been 24 hours of that stuff!!! I can’t even go outside!!

So somebody had better help me out!
