I would believe that what you find in Fold3 to be complete. However, you can procure these same records through a service provided by these message boards at:

I am unable to find his records in Fold3, however, if you can, note the number of cards in his file.

Then you can contact the above site and request they check his file, if there are more cards, then you can order his complete records through them.

Do you know if he was married and left a widow? If so, there may be a widow's application for pension some years later, ca 180, which can also be obtained through the service noted.
