Odds are it's a rebuild, and probably a LOT better off in terms of reliability because of that rebuild...
IIRC the electron guns in the EGP were essentially the same as those in other tubes, but the early EGP cathodes did not last as long as they should...So a rebuild with better made cathodes should be every bit as good as a properly made non-EGP.
