Another great addition on 4/23/08 is a 4-page document stating all the changes that were made for the 502 / 503 from the original 500 design. 

6/11/08 - Added a color reproduction of an original Diablo Accessories page. On it shows the original Diablo cover offered, helmet, face mask, snowmobile suit, patch and more along with prices. Pretty neat.

10/8/08 - Added a Tillotson HR Manual.

That is a huge amount of information. The packets are broken up in to a Technical Packet ($25) and a Memorabilia Packet ($20) to cover printing and postage. Please contact Bruce at if interested. I do accept payment using Paypal if that is convenient. 

If there is specific page or manual you are interested instead of obtaining the whole packet, let me know and I can offer these at reduced costs.
