There's a legend that Smith & Wesson or Colt bought out Philips & Rodgers because they were afraid that this supposed super revolver would put them out of business, but in reality, these things just failed to sell, not actually being that good, and the actual niche of being able to fire all kinds of random ammunition you might be able to find, is just so incredibly unlikely to be necessary in any manner of scenario, even many extreme and outlandish ones.
The extractor assembly is a pretty flimsy affair which you have to be very careful with, and general accuracy is poor with most cartridges. It seems the chambers (which will be quite unusually long for any cartridge which isn't .357 Magnum), in combination with the double-tapered forcing cone, makes for pretty mediocre inherent precision in most calibers and with most ammo. The cylinder is also made out of vanadium steel, which will explain why the gun wasn't just expensive, it was quite heavy.
It was some interesting thinking outside of the box, but execution wasn't great, and the concept is of dubious merit to begin with.
