General Thomas J. Stewart Medal

[Noor]

Hi guys,

Here is my new arrival - General Thomas J. Stewart Medal

Like I understand, it is very very common award to get. Information what I have at the moment:

The General Thomas J. Stewart Medal shall be awarded to members of the Pennsylvania Army National Guard and Pennsylvania Air National Guard upon recommendation of their unit or organizational commanders, for one hundred per cent attendance and excellence in drill, including annual field training, during any one year. Only one of these medals shall be awarded to any one individual.

My question is, from what period my medal would be? Also when this award was established?

To me, what shows some age;

- with the bent slot brooch

- do not "shine" under UV Light

- box looks nice age

- metal is darkened

I quess myself WW1-up to 20s-30s?
