Unidentified Unknown Enlisted WWI Collar badge

[GHB]

The attached pictures are for an unidentified enlisted collar badge from WWI era. I was advised it might be Selective Service, but I thought in WWII the troops working with Selective Service were officers and they used SSS.

I thought it might be Supply or Signals. Perhaps the dot was Morse code?

Help please.

It is neither Supply nor Signals:

Quartermaster (or supply) -

Signal Corps -

The dots are simply the background pattern. No significance.

I've not see S.S before... I've seen RS for Recruiting Service. So, Selective Service is certainly a possibility.
