''Again great info but I have problems believing that 7 prototype aircraft had "used" 262 parts on them. Perhaps remanufactured parts reversed engineered from the original hardware. I know this was still in the post war period but if this was actually done it was beyond risk, it crossed the line into stupidity.
BTW, excellent site!
It may go back to a time when engineers still had a feel and sense of materials as a skilled tradesman might. I don't immagine that the slat mechanism was all that difficult to inspect or complicated a mechanism.
