.....The ATF has also issued a cease and desist on the persons FFL…"

The ATF Cease & Desist order is just a registered letter from ATF to the FFL holder.
It calls attention to something the ATF will outline in the letter to the FFL that the ATF deems to be outside the GCA for the operation under what class FFL they have been issued.

It will demand that the FFL 'clean up it's act' in so many words and get straight with the rules and regs of the GCA.
The letter demands that the FFL read and then sign and return the letter to the BATF as proof of reading, understanding and that proper followup will occur.

If the letter is not returned, the next step is a personal visit from the BATF to further insist that the business and legal rules and regs be followed.
It can go as far as BATF revolking the license and closing down the business.

Most common recent C&Desist letters are for the change in rules over the parts kits and 80% frames being sold.
But they can be issued for any violations from constant paperwork issues, local licensing noncompliance, etc.

A local shop was shuttered a couple yrs ago over security issues. Easy access, constant burglarys. The license was finally yanked. The County Sheriff's Office took away all the firearms and ammunition to their property room. I don't know what happened to the non gun accessory stuff. They didn't do any gunsmithing or at least didn't adv they did.

Any FFL has to list 'Open to the Public' hours on their FFL application and followup Renewals.
It may only be a couple odd hrs a week,,but it must be there.
It is not actually for the public. It is for the walk-in Inspection and Compliance check of the BATF AND any L/E that has reason to inspect.

Up to a couple yrs ago, anyone with an 01FFL that was marked 'Gunsmithing Only' did NOT have to list Open to the Public hrs. You could do 'By Appt Only.
That has changed. Even the 'Gunsmith Only 01FFL issues now have to put down at least a couple open to the public hours on that application/renewal.

Those 'Open to the Public hours' may be a foot in the door with a L/E Officer assisting. With that and proof of ownership of personal property in the shop to retrieve, it may be a way of getting it back.

I think BATF may have the Hours on FFL's on file

Just some thoughts.
