I got my SBR Tax Stamp yesterday for my family trust. I mailed in the Form 1 in Oct it went to the investigator Dec 1st. Just FYI on how long it is taking for those waiting.
it can also very on just who the agent is doing your paperwork, some are slower then others. for some reason, a form 1 will always take longer (usually atleast 1 month or more) then a form 4.
I used http://arizonagunlist.com/How_to_buy_NFA_class3_weapons_with_a_revocable_living_trust_without_a_CLEO_signoff.html to guide me through my SBR.
I sent my Form 1 in 11/18/09. My examiner said yesterday that it came up in her queue and will be processed this week.
