Thread: modify this mold

I got this thing some years ago and I want to change it back to the way it was by filling in the eye holes.
I also want to shorten it and fill the collars so it pours between 3/8 and 1/2 ounce with pure lead.
It doesn't help that whomever modified it did a really bad job getting the eyes even.
Thankfully I only paid like $5 for it some many years ago.
Can I actually do this? Is it worth it to do all this modifying instead of buying a mold?

Or is this mold actually worth keeping as is? The only thing I have done with it is to fill it with hot glue and that didn't go as well as hoped.
