Bubble memory cartridge for Sony/Tektronix Model 370 Curve Tracer

Subject line says it all.

It's a real longshot, but does anyone have one of these lying around or know where I can get one?

Bubble memory? Does that thing use valves (tubes)?

No -  little magnetic domains that run around in racetracks patterns

I think I have seen that curve tracer in some dark and humid lab in the university of Manchester. Maybe I could look for it, they can use the newer ones I guess.  ;) How badly is this wanted?

I would like to find one too!!
