There were 4 versions of King Liberty:
Original King Liberty - shown in Niner's pic.(came as both a HP/LP or the LP version later settled on)
King Liberty #2 - this is the one with the art deco brace
King Liberty 2B - Pretty standard looking trumpet with a single radius slide originally
King Liberty 3B - a larger bore version of the 2B with several other tweaks as well
Don't forget King Liberty #2.5 - With the brace that looks more like a 'Pi' sign... kind of a fat version of the #1 brace.
Well, if we get into design refreshes and options, there are half a dozen for the original plus the mini, then the #2 had two refreshes I can think of off hand plus a number of options, the 2B had at least 4 variations. Only the 3B seems to have been short lived enough to not change at all.
