Hi Eric, also been doing a complete overhaul to my Kollsman,here's my bubble chamber after a repair and also a refill. Mine has a leaked bellow which cost me quite some effort to patch.
As for the liquid, I have tested both aviation fuel and the 0.65 CST silicone fluid as per Arthur has suggest in his article, both work well, bubble responds to even a slightest tilt. I would say that any liquid with a very low viscosity would do the job.
