slag chandelier converted to electric with gas works

Here are more pictures of the chandelier. First picture shows the fire in the gold part of the slag.

In the 3rd picture you can see where they attached the electric lights at the top.

#4 is a picture of the internal part of the gas works.

#2 is the very top of the chandelier, and the decoration matches the bottom of the gas works part. Could it be that when it was gas, this chandelier would be hanging the opposite side up instead of how it hangs now?

I think it could very well even be Handel. Anybody have any idea's?
