Do you Re-engrave your SBR/Suppressor if you if it is transferred to a different gun trust?

When making an NFA firearm, e.g. SBR, Silencer, SBS, etc., you will need to have the applicant name, city and stated engraved on the firearm before the NFA firearm is made. But what happens if I have an SBR, Silencer, SBS, etc. engraved with current gun trust information, but someday passes and is possessed by a different gun trust? Does the NFA firearm need to be re-engraved? No. Once the firearm is engraved with the maker's information and the NFA firearm is made, no future maker's or transferee engravings need to be added to the firearm. When transferring an approved ATF Form 1 NFA firearm to a new individual, gun trust or other legal entity, the ATF Form 4 would be used. ATF Form 4 firearms are already manufactured NFA firearms (remember the NFA firearm was made using the ATF Form 1) and don't need to be engraved with the transferee's information.
