Most of the survivors were from the upper positions on Scharnhorst, and a funnel hit would probably have been witnessed by at least some of the survivors.
Only four out of 37 survicors were from upper positions.
However, among the many inconsistencies noted by british interrogators, the following hits were reported by multiple survivors and detailed in ADM1-16833 , altough their sequence could not be reconciled (emphasized by myselfe):
 on the fwd. port 150mm twin mount
 on the aircraft hangar
 on the fwd starboard 150mm mounting on the starboard side near the funnel
 in the tween deck port comp. X
 battery deck port comp. IX
 on the fwd starboard 150mm mounting immediately before the final attack
 on starboard single 150mm gun
 on a FLAK Vierling
In addition to them, a number of hits whiches sequence was known have been recorded:
 hit on Crows nest around 09:25-09:30
 dud landing on portside between after twin 105mm DP at 12:15
 hit on starboard tween deck making a .5m hole in upper(?) side belt shortly after 16:50
 hit on A-turret causing a magzine fire shortly after 17:00
Notice a boiler hit or boiler hump hit was not among the hits confirmed by the survivors but a funnel base hit was, even though it´s particular chronological position remains to be unknown. Interesting.
