I would not bet on it
IMO this is an Original Zimmerman TK. But very ground dug...!
Wait for Carlsson to comment.
Know that these Zimmermans had 2 types of prongs.
with zinc and copper in the back
It's a cast fake, they really worked good on this one tough. The back says It all.
One of the first things to look for on this particular type of skull are the prongs (which are unfortunately absent in this case, except for the "stumps" sticking out of the cones). Authentic "cone-style" Zimmerman skulls do not have round prongs. When the prongs are broken, it can be a little hard to tell if they were originally round or flat, because the flat prongs on authentic skulls tend to narrow down at the point where they enter the cones. Here is some more info on these often fairly convincing skulls from a previous thread of mine:
"Cone"-Style Zimmerman Skulls
One thing to note are those strange bumps around the edge of the left cone -- I've never seen those before... I predict that you're going to get a lot of mixed opinions on this skull, as it has good and bad points. Personally, I wouldn't want this one in my collection.

I believe you're referring to CupAl, which consists of a bottom layer of copper, with aluminum on top (not zinc).
I don't quite understand... Are you saying that you personally dug this skull out of the ground?
