I bought a 4" in Brownsville, TX, in `61. The list price was $125.00 but Colt gave a $25.00 discount to LEO's. Unfortunately, I had to sell it and got what I paid for it.
I bought my second 4" in `65 in Tucson, AZ. The price was still $125 with the same LEO discount. I still have it, the box, and original bill of sale.
It's not for sale.
