Need Help Identifying this Elton John Pair

[ACE19914]

So ive been on the search for this pair of sunglasses for a while now, ive emailed sunglasses stores, gone in with photos, commented on youtube videos where hes wearing them, and still cannot get an answer to what kind of sunglasses these are. If i could atleast know the name and model id be able to find them im sure. Anyways these pair can be seen on elton in the late 60's and early 70's and are by far my favorite sunglasses ive ever seen. Here are some photos, hope i can get some help. Thanks Again, -Justin, 19, Syracuse NY.
