'Disney Swish' rocket bomb

I'm looking for good resolution pictures or drawings of this experimental bomb used during WW2 agains uboot pens and other bunkers.

A Google search yielded nothing but a pair of Youtube videos and a low quality scanned image from an old Polish book.

I know there's at least a color photo of the bomb and possibly a scanned sectional drawing. Unfortunately I couldn't track a working link for these. Can anybody help?

This rocket bomb was used in the closing months of WW2 against German submarine bunkers. Apparently some of them could withstand a direct hit from a 12000lbs bomb and both the RAF and the USAAF were looking for ways to destroy or damage them without having to resort to overload the bombers of the day (mostly Lancasters and B17) with 22000lbs bombs. These were so big that the bays had to be modified and the bombers incurred in a severe speed and maneuvrability penalty, making them an easier prey for AA fire and the fighters.

The 'Disney swish' bomb was a 4000lbs rocket assisted, armour piercing bomb with a terminal velocity of over 700m/s (c.a. 2000fps). Dropped in pairs at about 6000m (20000ft) it fell freely (some sources says it was a retarded fall design, meaning a small drag chute would stabilize its descent and angle) until a delayed fuze would start a cluster or rocket motors propelling the bomb into a shallow, high speed dive.
