Scarce Pair of WWI US Air Service Officer Shirt Collar Insignia

Scarce pair of WWI United States Air Service Officer shirt collar insignia in nickeled bronze.

Circa WWI

Approximately 7/8" x 5/8" each.

Nickeled bronze.

Horizontal pin with 'c' catch.

None.

This is from a WWI USAS collection which we will be listing more of over the next few months. MBX12 LBBEX2/15

5- (Very Good+): The collar insignia have seen moderate wear and oxidation.

As with all my artifacts, this piece is guaranteed to be original, as described.
