I would also bet the All American has a much better gauge.

I need to correct my self it seems the presto still uses NPT but they have a contration to screw it into so far i have seen 3 different gauge setups.

Remember on a gauge or NPT threads 1/8 pipe threads will look like 1/4 inch the reason is pipe is measured on the inside not the outside like a bolt.
