If you've been following my story over on the wrench pages, I bought an old tool box and have been going through it's contents. Well, this one is waaaayyyy out of place. Aircraft Tools Inc, 9 and a half inches long, 4 and a half handle, and a spring steel "feeler gauge" tip with a unique cut out shape on the end. This one might be a wooly booger to track down it's use, but the company is still in business since 1949 so I may be able to contact them directly.
