Speakman Thermostatic Cartridge Replacement

I'm looking for a replacement for this cartridge. Back in the 90's when thermostatic protection was mandated in the code, many companies with high end faucets would adapt their trim to thermostatic valves that had already been developed. This shower valve trim is Newport Brass and no longer provides hot enough water.

Thanks, Frank. I have since found out that Speakman has redesigned their thermostatic cartridge so that all three pieces that you see above are now one piece. Unfortunately, this would not work for this particular shower valve because it has a very long stem and the new Speakman all-in-one has a very short stem.
I was hoping to find some some old parts on eBay or elsewhere, but nothing so far.

Ben: How do you think the extension is attached to the short stem? I didn't see any obvious set screws.8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

It looks like there is just a spring clip that slips over the outside:
