The incomplete part is the main drama. It's a problem for these older NFA items that may not have seen the light of day for 40 years or more. Especially the registered dewats. It basically on the owner to keep the records. Because the folk that require the paperwork can't be bothered to keep up with THEIR copy!
No reason getting worked up over the issue, as junebug1225 hasn't been on site since 20 minutes after his post...
