Python is Python. They don't designate them re "model numbers."
You've got a Python. That's all it is. A Python with aftermarket grips. Pity you don't have the original grips. The originals add to its value. Oh, and the gold filling in the lettering detracts from the value. I've got a Smith and Wesson 25-2 with the same thing. One of these days I'm going to remove the gold from the lettering.
There was a time when that was "cool." Sort of like those idiot wheels that keep turning even after the car stops.
It's not cool anymore.
