Good find. You have to be willing and able to strike when the iron is hot.
I never see a Python that isn't in new, or near new condition. A few weeks ago I spotted one in the case at the LGS. Not the "collector case" but the regular "used gun" case. It was worn and dirty, but checked out mechanically. I stuck it on layaway, did some research, found out it was made in 1964 (not that, that was important really). Picked it up a week or so later, cleaned it up, and it turned out to not as rough as I thought it was.
(Shameless show off picture)
The day I picked it up, one of the salesmen came by and said "Oh...You got it. I had a customer come in the other day who said he saw it, but figured he'd leave it a day or two."
