Read Brooke's Journal when it comes in to you. Much of the armament came into Confederate possession came with the capture of the Norfolk Yard.

Another possible source of information would be Record Group 74 in the National Archives. Some archival bushwacker made off with an armload of the records sometime in 1987, much missing. Hey, everbody reading this post should request something from Group 74 just to apply some heat. The definitive answer might be in the stuff remaining.
