A big thank you to Bali-Nut, a.k.a. Moose for sharing some of this material!

Here's what Moose had to say about it:
"This is a scan of a price list from Sunrider Corp, 1983. Sunrider corp published the Manipulation manual for the "Balisong" Knife, by Wei Ding, and Tom Wei Toi. When I bought the book, it just so happen to have the price list in it. It also came with one of those generic PCC brochures.
