Hi Kweassa,
>Yes, I was looking for the same thing myself.
Here's some (sketchy) information on Western torpedo sights:
From what I've read, the torpedos had a mechanical analog computer that was fed with the target ship's relative course as well as with its speed. Just before release, the pilot (or torpedo aimer) would flip a switch to compensate for the target's manoeuvres (if any), indicating whether it turned at him or away from it (switch centre position was for targets running straight :-)
The computer also required advance setting of the torpedo's speed and (I think) also of the release range.
I'm not sure whether special sights were used for aiming torpedos, but my impression is that the aircraft just flew straight at their targets using their usual reflector sights.
(This information is from memory while I'm trying to recall Dunstan Hadley's "Barracuda Pilot" and a Jet + Prop letter to the editor. The Jet + Prop letter featured a photograph of the command unit of a German torpedo computer that seemed to have all the features Hadley mentioned for the British system, too. The neat thing about the German system was that relative course was set by turning a knob in the shape of a little warship :-) The Luftwaffe must have its share of reverse-course shots during excercises, I bet! :-)
By the way, I believe Hadley also mentioned that they had a converted instrument flight simulator (certainly the "Link Trainer") that served as visual torpedo bombing simulator.
