Strang fins on german SD 50

[MINENAZ16]

Hello,

Is it a modification to increase space ?
Fins of the sd50 seem to have been reduced.
Any idea ?

They look like the whistles they place on the bomb fins so it makes a whistling noise as it falls from the air, designed to terrorise the populace who they are bombing, bit like the Stuka sirens in a dive.

Yes fins are fitted with whistles ("Jericho") but my question is about width of tail unit.
Maybe an optical effect but fins were usually wider

Having a second look i think the fins are the same as normal, looks like the bomb in question is shown at a angle.

This picture is so heavily and crudely retouched, one cannot draw any conclusions.

No, it's an SD 50 - division line between the warhead and the tail fairing is pretty clearly visible, plus holes for bolts fixing the fairing.

On the other hand, it seems to be a regular SD 50 - and I can see nothing strange with its fins.
