Ship ID book replaced by Loose Sheets and Deck Gun Question

[Aussie Moggy]

Just bought the Steam version of SH5 and an still working up my skill level, especially the full manual targeting mode.
I have the Mega mod installed and it is very good, even though I don't speak German, I guess I will learn some by osmosis

I have tried searching for an answer to the below without luck.

The two issues I have are;

The Ship Recognition Manual is now separate sheets of paper with only a side view and no link (that I could see) of sending the mast height to the TDC.

I have downloaded a couple of ID book mods ie, Enhanced Ship Recon Manual V.2.1 but it mad no difference, still the same sheets.

Is there a way to get the old book back without having to edit the game Data directory etc ?

The other issue I have is with the Deck gun, how do you aim it ?
I tried the Tab key, but it did something else (can't remember what now).
Stock crew are either drunk or have only had 5 minutes of training, their gunnery is beyond woeful.

Cheers
