YES Thorsten, Schmalenbach ( 2nd Artillery officer and Flak responsable ) took precise note of the 105 mm heavy flak shells expenditure on his report attached to Prinz Eugen KTB.
Directly from Schmalenbach report thanking Ulrich translation :
Experiences on Board.
At the commencement of fire, the serving crew of the heavy and light flak was transferred to the starboard side's protective shielding in the lee of the line of fire.
This was because the flimsy shielding provided for the [fire-control] stations [on the port side] appeared inadequate in anticipation of the hostile [heavy] caliber [hits] and shrapnel we could expect.
Furthermore, I assumed that the battle distance would not slip below 150 hectometers [ = 15.000 meters although it did, Editor].
At the order to open fire against "King George", the services of the starboard side [flak batteries] were first brought to bear.
Thus, (flak) Battery "Dora" expended 60 rounds of explosive shells with a firing rate of (two rounds per) 5 seconds, accounting for a firing duration of 80 seconds [average of 22.5 rounds per minute per barrel: Editor].
Battery "Bruno" expended only 6 rounds. Both (gunnery) leaders ceased fire on their own [volition] when the maximum [firing] range was reached.
In both batteries, the [fire control] station's computations and the entire transport of ammunition by the portside (crew) was accomplished calmly and without interruptions.
Credit is also due to the stand-by crew's assistance, although they only saw moderate action.
and more about the Sunderland after :
During the subsequent shooting at a Sunderland flying boat by Battery C, two detonation failures or [fuze] setting errors were observed by me.
Their causes could not be explained (determined). Most likely, preset ammunition was fired without resetting the fuzes.
The 105 mm guns were type C/31 and you can read their characteristics here in.http://www.navweaps.com/Weapons/WNGER_41-65_skc33.htm
Gun designation : B-Bruno was the one aside the main tower forward, C-Caesar was the gun in the middle aside the crane on the main deck level and obviously D-Dora was the one aft.
According to the officer I have interviewed last year the shells felt all short and consequently they ceased fire, he could still not beleive himself he did participate in that battle with his 105 mm guns firing at a battleship of KG V class : the HMS Prince of Wales.
