The new Pythons are going for $1400ish new and are all stainless,
AFAIK. That makes the older ones more valuable and they are usually close to double that. But this one, being a custom issue, is like a left-handed 6mm rifle. Lots of lefties, but few want 6mm. Lots 6mm rifles, but few righties want them. You just have to find the right buyer.
