It seems a 'T-4' bomb sight was used - but what is that?

"...my job was to maintain the serviceability and the accuracy of the T-4 bomb sites [SIGHTS] to support the Canberra bombing and training programs...."

I will do some images of the bombsight, computor and associated controls on Tuesday and post them. "Yes Computor"

The T4 was a follow on from the T1 (Lancaster) and from what I can see the T2 was fitted to early Canberras then upgraded to T4.

Thanks very much 'Aardvark'.

F-16.net in the F-35 sub forum of all places astonishingly in an A-10 v F-35 thread a bunch of information about the T-4 has been posted along with links to images.

Just thought this NORDEN bombsight story may be of interest in PDF attached.

Norden Bombsight - AIR & SPACE Magazine May 2020 CHRIS KLIMEK

IT TESTED MORE IMPRESSIVELY THAN IT FOUGHT, BUT ITS MARKETING HIT THE BULLSEYE.

“CARL L. NORDEN’S bombsight calculated a bomb’s drop point based on the delivery aircraft’s speed, range to target, wind, and other variables, causing it to be touted during World War II (among those with the security clearance to know of it) as a miracle device that would destroy targets with pickel-barrel accuracy from 20,000 feet. The U.S. military spent $1.1 billion in 1940s dollars to build 90,000 Nordens, each one a 50-pound analog computer comprising 2,000 intricately joined parts including gyros, motors, gears, mirrors, and levers. If their aircraft were fatally hit, bombardiers were under orders to destroy the secret machine rather than allow it to be captured.

While showing great promise in daylight testing, in combat, it failed to produce notably better results than similar devices fielded by other air forces. By the time the United States entered the war, the Germans had copied Norden’s synchronous- release, gyroscopically-stabilized design thanks to a spy at Norden’s factory named Hermann Lang.”

NORDEN Bomb Sight from the PDF above Air & Space Magazine May 2020.

Photo Caption: "This Norden M-9 is installed in the B-17G Shoo Shoo Baby, assigned in 1944 to the 91st Bomb Group based in England. All Nordens had a rubberized eyepiece, which often created a black circle around the bombardier’s eye."
