Just a quick question to clear up something for me. Why the different engines on the DC-6? There's a CB-16 and a CB-17. What's the purpose or thinking behind this?

For those that don't know, the R-2800 CB-16 and CB-17 are actually identical engines - you can easily convert one to the the other with a few adjustments. As I remember, the CB-16 was the first engine to be produced, and ran on standard 130 octane (?) aviation gas of the period. The US military had better gas though - 145 octane, and that was allowed to be sold on the civil market starting sometime in the 1950's (if you had the right politics). P&W decided to certify the CB-16 using the better gas, and called it the CB-17. It gives the plane more power, and allows higher performance or (more likely) more payload. The planes here at CC that use the CB-17 are the DC-6A, the DC-6B CB-17, and the CV-440.
Hope this helps,
