Hey Rich:
The second vid in your second post starts with one of the 487 Sqn Mossies on the 9 October 1943 raid I referred to earlier in the thread.
I think the fjord raid is at Nordgulen, certainly this photo at the Australian War Memorial site would suggest so:
http://cas.awm.gov.au/photograph/SUK13677That link has the raid being undertaken during January 1945, however I believe it was actually 5 December 1945. The Banff wing strikes (including Nordgulen) are described in some detail on this site:
http://www.scotshistoryonline.co.uk/sorties.htmlThis German site describes the damage caused:
http://www.wlb-stuttgart.de/seekrieg/44-12.htmThe translation for the Nordgulen attack is: "34 Mosquitos of the 143. , 235. and 248. Sqn. RAF (” Banff Strike Wing “) attack the 1st northbound part of the convoy BE-1075-AL in the Nordgulenfjord and damage the freighters Tucuman (4621 BRT), Magdalena (3283 BRT) and the ammunition transporter Helene soot (993 BRT). Protection by flakships V 5102, V5305 and V 5306."
As I've not spammed the thread with "stub exhaust" pics for a while, here's another. Caption speaks for itself (a "Noball" was an attack on a V-1 site).

The squadron was at the time flying about 1/3 of its sorties in daylight, hence the *cough* stub exhausts (dead horse flogged).
The Australian National Archives have done an amazing job of digitising WWII-era records, including squadron Operations Record Books. Here's the relevant page from the 464 Squadron ORB. CHL Foster, the gent mentioned in the pic above, flew on this raid in LR383 (if you right-click and save as, then zoom in, it's actually quite legible, despite the way it appears here):

Karnak - I still have to check the charts re: your question - can't remember off the top off me head again which was the "dog" aircratft, and what condition it was tested in when.at what weight. I think the drops accounted for around 5 mph or so.
