Elco vintage engraved "Happy 11" 12kt gold filled charm on 14K GF necklace

Excellent vintage condition, shows minor rubbing to gold plating consistent with age. This sweet necklace could have been gifted for an 11th birthday or anniversary and should be once again. Chain is 14kt gold filled and I can't make out the maker's mark. Clasp functions perfectly. Please see photos for measurements.
