Piggyson's files have been asked for so many times, but unfortunately we never manage to find them.
I don't think this is what you are looking for, but it's all I could find.
Modeling a weapon sight.
If anyone has copies of the models Piggyson released I would greatly appreciate it if someone can send them to me. I'm looking for the UH60 Model, Zodiac, Stationary Weapon Model.
I found the character ones.
