The puller is the easiest thing to make with a lathe and mill here's where a photo of the device is located. https://www.chaski.org/homemachinist/vi ... sure+gauge probably a 15min little project and pretty crude at that.

As for the duplex gauges. I thought it was covered earlier here but the issue became finding a donor gauge that would work in a scale that would be useful, as making bourdon tubes and gearing is something beyond my knowledge or what I think look the market could even bear. Maybe I could make one for the larger scales but definitely not 1.5". If someone's interested in working on the project to make a few let me know. I would be happy to help with the art work needed as well as trade notes on a donor gauge to use, but I just don't have the time right now to make it all happen.

I was interested in a duplex gauge for air pressure - reservoir pressure on one side and brake cylinder pressure on the other. I spent a bit of time trying to find someone that made them in scale or nearly scale size. The closest I came was a 2" gauge. These were made in India and I suppose available in various pressures but I didn't followup to find out. https://www.indiamart.com/proddetail/du ... 49230.html

Duplex would be very interesting, Especially if they could be made like the prototypes. Ive not seen many duplex gauges in the hobby.

Something like these would be cool, but likely a lot of work/$$ to make.

Here is an English Smiths gauge, in a 3-3/4” 2-6-2. It reads main res and brake cylinder.

It took a while to make them, but I now have some more of the original and most popular 2" 200psig gauges available to sell at the following website;
