Of the seven revolvers Colt named after snakes, the rarest is the Colt Boa. Only a single production run of these were made totaling just 1,200 guns. They were made in 1985 as a custom order for the Lew Horton distribution company, which wanted something unique to offer its buyers. The Boa was an intermediary between the standard Colt MkV and the high-end Python. It was a 6-shot .357 Magnum with a full underlay and ventilated shroud. The only variation was in barrel length, as half were made with 4” barrels and half with 6” barrels. The serial numbers were “BOAxxxx”, with the 4” guns having odd numbers and the 6” ones getting even numbers. Five hundred of each were sold individually, but the first 100 of each length were packaged together into sequentially-numbered pairs in fancy cases.

The Boas all sold in 1985, and they are now the hardest to find for the Colt Snake collector. This particular pair is a gorgeous example of an original cased set, numbers 43 and 44.
