Heckert Glass? Vases

Possible Fritz Heckert vases, at least the glass. I believe they are Heckert because I have another signed vase using the same technique of multiple types of flowers with black stems and leaves. But as you can see in the third picture, the main reason I got them no matter who made them was to go with the clock. I have had the clock for almost 30 years and have never found the clock ornament that belongs on the top. I know what it looks like, but have never seen one. So when these gargoyle vases came along I grabbed them.
