The entity (ie. LLC, S-Corp, etc) doesn't cease to exist just because it gave up its FFL/SOT. As long as the entity legally exists it can retain ownership of any keeper NFA items.

This.
Yes, the entity (or SP) retains ownership/registration of whatever they already had at the time their FFL/SOT was relinquished (except post-86 MGs aka "post samples").
If they're giving up the FFL too, they close and turn in their last 20 years of bound book(s) to ATF's OBRC.
Those (former FFL/SOT) individuals or entities can also transfer tax-paid on F4 just like any private citizen can do (only exception being "pre-sample" MGs can only be transferred
to a
current holder of an FFL/SOT, or any government entity).
Remember... NFA transfers (and the correct form to use) depend on the status of the firearm, and the statuses (SOT/government/estate) of the transferor
and transferee.
