HI Early on Sulzer worked for James Knights, later CTS. I suspect he got at least some of his crystals from there. Rumor has it that he bought large batches of crystals and monitored them for months / years before using the best of the batch. That's a fine way to make a small number of OCXO's. Not so great for grabbing a replacement part.
HP made their own crystals for quite a while. They also bought parts from just about everybody in the business for various applications. My *guess* would be that the 106 has an HP made crystal in it.
