Boot Camp platoon

I went to SD boot camp on 7 June 1974. I’ve looked through my DD214s and I’m unable to find what my platoon number was. I’m pretty sure we graduated in Sept 1974. Reason for my search is I’m wanting to get copy of my boot camp photo album. Without platoon number all places with them can’t help me. Any help in this matter would be greatly appreciated. I would like to leave this with my family. I can be reached at aj_jm964@yahoo
