Vintage Sterling Silver Eagle Pendant Signed Excellent Condition

Description

Very impressive and well made vintage sterling silver eagle pendant in excellent condition.
The pendant is marked sterling on the back and it is also hallmarked with maker's mark but we have not been able to identify the maker.
The mark is a capital "S" with "I" running through the "S".
The pendant has no bail, but the chain is supposed to run through the eagle's jointed wings at the top.
Very pretty design.
The eagle measures 1 1/2" long X 7/8" wide.
The chain pictured in our first photo is not included.
The auction is for the eagle pendant only.
