Great guns, I've had deals set up for two different Pythons over the years, neither happened. The first was in 1975, a 4" for $200, bum agreed to a to a pay day purchase, he had sold it (for more money) when I showed up on pay day with cash in hand. Second was about 6 or 7 years ago, had a deal on a 6" for $1000, had the money in my pocket and the gun in my hand when the seller decided he just couldn't part with his baby. I think he still owns it to this day, I can respect that. Between the two deals I had a Smlot (or Smython) made for me with a 3" Python barrel on a round butt S&W M19 by a great pistol smith. Not many of them in this world, real fine gun. Gunsmith still advertises them as one of his signature creations today, I think mine was his first.
Now the bad news, Zoot guns had to be in production by 1949, Colt didn't start selling the Python until 1955. Still a great gun, enjoy your new baby.
