SBR Trust Engraving Requirements

I’m delving into the NFA world with an SBR registered to a trust. Now I know I need to engrave the lower with the trust name, city and state. I need to know if the full name of the trust needs to be engraved. Lets say my trust was called the “Generic Revocable Trust.” Could I just have “Generic Trust” engraved on my receiver, or would I need to have the complete name engraved on the receiver?

I would do complete. Better safe than sorry…
