I sent you a PM with my cell number. I am heading to bed in a 1/2 hr as the weekdays are long.
The ONLY time fingerprints or photographs are submitted is when you are submitting a form (either form 1 or form 4)
As mentioned above, ANYONE that is listed as a trustee at the time of form submission MUST fill out a F5320 Responsible persons questionnaire. Basically its the same questions as what you fill out on a 4473 when you purchase a firearm. They must also submit fingerprints and a photo.
-Story time -
My son turned 18 last month. Legally he is able to posses short barrel rifles and suppressors that are owned by the trust.
The only thing I have to do to add him as a trustee is to make a amendment, print it and sign it. It isn't filed anywhere. I don't have to send anything to the ATF. Nothing but doing the amendment.

I can discuss this more over the phone if you like.
