vintage 1964 hughes aircraft company robinair model ld.101 leak detector. detector is untested due to age of components. leather case is coming apart at seams. snap latch has rotted off. but I do have it. case has lots of wear. and leather is possibly starting to rot. detector has date of 1964 written on tape under detector chassis. measures 9 inches long. 5 1/2 wide. will consider offers. thanks.
