Hi A little more background on FEI.
For quite a while they were a major supplier to the high end of the military and space end of the oscillator business. A lot of their work was on classified projects. They branched out into the atomic clock business and also into the sub system business. Nothing they did was ever going to sell on the cheap. Eventually this got them in hot water with the US government. The settlement of the case effectively barred them from competing on DOD projects. As a result they turned more to the telecom and commercial end of the business. The case design you describe would have been very typical for a double oven back in the 1980's. The Vectron CO-246 series is one example of a similar part. Your part, or at least it's design likely dates to that era.
