vintage Mr Christmas blown glass birds clip on tree ornaments spun glass tails blue peacocks

Vintage Mr. Christmas brand hand blown glass bird ornaments with the spun glass tails, all in good condition in original box. (Box has wear, torn and missing cellophane window).

These don't seem to be marked or dated that I could see, not sure but think they are probably German. They measure 6" long tip of beak to the glitter edging at the end of the tail.
