Need help with Sterling/Gold Filled pin

This pin is marked in four places. It looks like it probably started as two pieces, one silver and one gold-filled, which were then soldered together. The top, silver piece, is marked STERLING and has a maker's mark. And the bottom, gold-filled piece, is marked 1/20 10K+STER and has the same maker's mark.

I don't recognize the makers mark. Can anyone help...with the maker's mark or any other info on what this pin might be, if anything?
I just got it today at a church bazaar. It was marked as Coast Guard or Navy?

 

Ohhh....when King sees that .....!!!!

Hey Libby where ya bin ??

 

I know! It has been a while, huh? So tell me, what do you know about it??
I'm on the edge of my seat...

 

According to the following website it is an Officer and Chief Warrant Officer Cap Insignia.

"This device is worn on the combination cap and a one-half size miniature version is worn on the garrison cap."

It says "in 1941 the eagle was changed to face to the right; to the wearer’s sword arm." As yours is facing to the "wearer's right" yours would date after 1941.

"Two gold colored crossed fouled anchors with burnished silver colored shield surmounted by a burnished silver spread eagle.."

If you Google: Navy eagle, shield, anchor pins, up will come a multitude of images of them.

BTW, believe H&H Hillborn and Hamburg was the manufacturer of this insignia per the following website. It seems they used 2 different logos with yours, a spread wing eagle with HH, the most commonly seen.

Need to scroll a good 1/2 way down this page to H. & H. Hillborn and Hamburg.
