Unless the items have been held by a 02/03 SOT for the estate there won't be a new 4473. For individual NFA Form 4s or 5s, there's no need for a background check because that's been done by ATF. If a 4473 is done the check is bypassed and you just tick the corresponding NFA box. This is different than a Trust stamp where the check is done because they're uncertain who from the trust is picking up the NFA item.The Annoyed Man wrote: But with a Form 5 transfer of an NFA item, does the transferee still have to fill out a 4473 and undergo a background check...
For the form 5, two copies go to ATF, one notification goes to the CLEO, and eventually a copy of the Form 5 comes back to the transferee.
