They are rebadged prestos which either a genuine hoover or genuine presto will work but if the 12 cup glass top is any different it might not work as mine is a 9 cup hoover but if all prestos are the same glass top I'll be happy to learn that too.
Thanks for your help and input.

I have brand new Presto glass percolator tops that you need. The original Hoovers are triangular in shape verses the round ones that Presto used. Doesn't matter if they are 9 or 12 cup size the glass is the same. If you are interested in one you can reach me at [email protected]. Steve
