This knife has been made at least 20 years ago. Should outgazing be a problem, it would have shown...
Not necessarily. Some have gone 100 plus years, before starting to outgas, others weeks. Age is no "guarantee" that it won't eventually outgas. Chances are celluloid will eventually outgas. Some lots/runs just take longer than others. Some colors are more apt to outgas, as well.

store it apart from your other knives, "just in case".
Once they start to outgas, there is no cure. Best you can do if it ever starts, is to pop the covers off, and dispose of them, preserving the knife.
In that case, you can have someone like
glennbad
put a new set of covers on, or if you're handi, fit a pair of covers, and glue/epoxy them on yourself. (using glue/epoxy only you don't have to take the knife apart, like you will if you use cover pins.)
Good looking knife. Are you sure the covers are celluloid, and not a acrylic? If acrylic, they'll never outgas, or give you grief.
