I have the 10.5cm Deck Gun upgrade working fine now.
It only supports 105mm HE and 105mm AP rounds.
I can not enable any special effects in Shells.sim for the ammo because it results in CTD but everything looks fine with out the special effects enabled in the SIM file.
I'd like to get 105mm AA and 105mm SS working at some point.

All of the Light and Heavy Flak guns are working now.
Heavy Flak Guns are only available on Type-VIIC and Type-VIIC/41 Wintergarden. Heavy Flak Guns require a Heavy Flak Mount (S01 or S02) and the Type-VIIA and Type-VIIB do not have these mounts.

Added Alberich Coating for Type-VIIB just in case someone keeps this boat for a while.

I've been trying to add the Periscopes as Upgrade options but I suspect that this may require editing of Menu to add another Sensor Tab.

I want to add the Schorchel as upgrade option. When time permits for both of us, I need to get together with TheDarkWraith to work on this.
