The bike in this thread's got the cranks:

From that thread, everything you wanted to know about bent cranks but were too afraid to ask:
Article from "Cycling" 1985 (UK magazine):
Review from "Cycling" 1981:
Advert:
As usual, there's nothing new, how to ride long cranks without having long legs:
And here's time trial legend Ian Cammish:
If you look at the crank with the pedal at the 12 o'clock position, it looks like if you push the pedal straight down you can still turn the crank, but of course you can't. So it's a bit like an optical illusion.
Some UK time trial riders like to use a huge gear and long cranks, and the bent cranks supposedly help with pedalling past the top dead centre, ie crank at 12 o'clock. Look at what the advert says. Don't know if anyone actually believed it though.

As an impressionable teen i used them in the late 80's. The benefit, as with alot of stuff, was all in the mind.
Lord knows how much a period TT funny bike would cost to build these days with the price and rarity of stuff like PMP cranks, Kronos brakes, Assos rims, 80mm front hubs, titanium stem and BB, super record rear mech, etc
