KVG were an exceptional quartz company. Last I heard of them they'd undone a takeover and were an independent private company again. They had been gobbled-up by Vectron at one point.

I had some inverted-mesa 100MHz fundamental VCOs done by Vectron.... they were no slouches either, but they did go on a buying spree of other quartz firms.

The most exotic crystal filters I was ever involved with were special low distortion jobs for NPR testing, where intermodulation was the big trouble. We found only C.E.P.E part of Thomson-CSF could make them and the up-front engineering charges.... were in the jeepers! league.
