I've looked at these pictures in more detail. Col. Compton's knife does not seem to be the one that is pictured being worn by Col. Moore with his DSC. That one has a dark wood (?) commando handle, with all-medium spacers, whereas Col. Compton's knife has a stag handle and WWII (?) mixed spacers.
Regardless, Col. Compton's knife is historically interesting and Gen. Moore's son says he may have taken it to Vietnam... However, I've asked him to forward additional pictures if he comes across another Randall that matches the one pictured in the DSC photo. I'm going to post Col. Compton's knife in the WWII Randall line too.
