I would say what you have is a boost compensating, non adjustable, blocking fuel pressure regulator with integral sediment bowl filter.
There must be a spring that presets the pressure and the top portion you could not split adds pressure when the boost comes on. Any diaphragm with similar dimensions should work, but I'd be hesitant to mix and match given the need to balance fuel pressure with boost pressure.
I don't think you will find a replacement all in one unit with modern materials. The glass bowl portion is not something manufacturers would see much demand for the last 30 years since EFI took over the hot rod market.
It would be easy to find it as two pieces: a modern boost compensating, adjustable, blocking regulator and a separate sediment bowl/filter (or modern disposable filter).
You can get the regulator portion with a built in gauge, a threaded port for a gauge/sender or just put a T in the line between regulator and carb.
There are also electric fuel gauges with 0-15 PSI range that probably covers what you need, and no fuel line needed in cab.
some examples i have no first hand experience with:

That is terrific information, thank you. Given that I am re-plumbing the entire fuel system from the tank to the carb and I already had plans for an inline fuel filter cartridge system, I think I can safely eliminate the glass bowl filter. As for the fuel pressure gauge, there is already one in the truck and at this point I wasn't planning on eliminating anything but could be convinced, , the line from the existing glass bowl setup to the cab does carry fuel and goes to the fuel PSI gauge ((1-15 PSI). The other output barb at the top of that regulator joins at a "T" another rubber hose line from the back of the carb plenum to feed a second gauge in the cab labeled Pressure (1-10 PSI)
I'd like to eliminate both of those gauges, but specifically the one bringing fuel into the cab, since I already eliminated the fuel tank in the cab. I'm guessing that the regulator that you showed can have a gauge mounted directly on it instead of pluming fuel into the cabin. What about the other gauge, it doesn't seem possible to eliminate it without losing some information.
