my nonexistent pressure cooker

I bought a Presto 8qt pressure cooker (model 0128204) off Amazon a couple of years ago and was looking for regulators and other parts for it.  Apparently that model number is a figment of my imagination even though it is stamped in the aluminum pot.  As of this writing there were three (3) google hits that positively listed that model number, and none had parts.

So I called Presto and asked about it. The rep seemed to sidestep the issue a bit, but when I asked if the listed 0128202 used the same gasket, overpressure relief and regulator she said it did.  She also advised the only regulator for this unit is 15#.  I would like to have a 5# and 10# for it like I do for my 22qt Mirro canner.  10# would be a bit gentler on my agar media, I suspect.

Posting this bit of trivia here so some other lost soul with a 0128204 wouldn't have to duplicate the effort.
