49 parts book?

Could it be someone had it apart and parts didn't make it back in?

No, these parts are way different than anything I've seen. As they don't list part numbers for even the usual pieces individually makes this harder. It appears that the lower valve, the center valve body and the upper spring were all made as one part rather than three as what we are used to. The spring itself is actually four individual pieces of spring wire staked into the valve/body. the other spring isn't necessary because the parts it is supposed to work against are all part of one part. If that makes sense. This fork also has the springs listed in your parts book as sidecar use or on a shop dope as simply heavy duty.
