A new draft version of Form 4 for transfer of a NFA firearm was released by the ATF. The new form includes reference to the definition of responsible person. I interpret the definition to include current trustees, not successor trustees or beneficiaries. If your NFA gun trust was prepared prior to release of the new Rule 41F in January 2016, I suggest you have your document reviewed to see whether it unintentionally expands the definition of responsible person to more than just current trustees. Although not urgent, this issue should be reviewed prior to purchasing a new NFA firearm.
