Sorry Les but no. I was lucky just to find a working unit in SoCal (Superior Automotive Engineering, Anaheim, CA). These machines are no longer in production and the one I found was over 50-years old.
The owner tested the distributor while I watched and recorded the changes. We made no attempt to correlate timing to vac or press. My mission was simply to find out what happened when I put pressure on the vac port and just how much timing the boost retard pulled out.
I had been running my little car without any vac advance and was running +35 deg. of advance at idle in order to get it to come off the line. Running 1-bar boost without an intercooler and reading this forum I was beginning to get a bit nervous about the grenade in the back seat.
If I pull the distributor for any reason, I'll return to Superior, get some data for posterity and post it.
