What I am getting at is this. The TM's you have, all have a date. And some will have printed on the cover, or printed on the first 1 or 2 sheets, a change number, IF it has been changed to correct something misprinted, or to give you some more info not in the original TM. The TM date is important, as it will tell you if you have the newest TM. The number of changes, (if there are changes) is important, for the same reason as the TM date. If you have outdated TM's, or the TM's that you have do not have the right Changes, then you are using a document that may not help you, may not inform you of something important.
To the right of the TM's, it looks like you have at least 2 change documents. To the left, you have 2 copy's of the Generator -10 TM. There are also 2 copy's of the LO, (Lube Order) for the generators. There is also a copy of the basic Trailer TM. You are missing a bunch of other TM's. All the Tm's for this PP, (power Plant) have been up loaded to the SS TM forum. With, as far as I know, all the latest updated TM's and changes. Except for TM's that are not allowed to be distributed to the public.
Why don't you list here the TM's, by number, date and changes, (if any are in the basic TM) and what changes are in the pile to the right. List the change number as well as the TM number. Hopefully, the changes to the right, are for the -10 gen set TM's. Hopefully, the changes are in sequence to the TM's. By that I mean, you can not insert change #4, before inserting changes 1,2 and 3.
