JMorris, (put your damn first name in your posts will ya): I risked life and limb to go out in the beautiful weather to take photos of the target design. My oxygen hose doesn't reach that far... I took the risk of passing out and being eaten by a bear. Don't know if these will help you or not, wasn't really sure what I was taking pictures of. The system really seems pretty simple, just a few small springs and aluminum rods protected by the steel frame. Gonna take two posts for all the pictures' Jack Continued on next post.
