I still need some high quality reference oscillator. Do you have any clue how much those Wenzel oscillators cost? There wasn't any prices on website, may be the only way is to ask? There seems to be interesting alternatives for the output oscillator too (to clean the LPRO signal). One of those was even named "timekeeper". Maybe it could be wise to buy one and use it for phase noise measurement first and then put it in permament use as the output oscillator of the reference, when the desired loop bandwith is known. But of course if those units has price tag with four figures or so then this is only daydreaming... :-) -- 73s!
