Not legal in CT anyway, unless produced in state.
Why? Because of a state or county/city law or iis because of the Lacey Act? If it the Lacey Act - that was overturned last year(April, 2017) by US superior court. The court ruled with USARK - in that the prohibiting interstate trafficking of large constrictors(non-native species) was an illegal usage of the Lacey Act(which was designed to protect native endangered species). So it is now perfectly legal to get retics and burms out state(so long as your state/local laws allow it.

I actually got my pair of pure dwarfs from Bob Clark in September, 2017.

I've heard that and also that the temperament between half dwarfs and full dwarfs is vastly different.
Well - I have heard that infamous temperament of the pure Dwarfs really only really applies to the first two CB generations from WC stock. My are F1/F2 - so they still have the infamous temperament, even though I have been attempting to tame them for many months. The F3 pure dwarfs tend to have a much better temperament - more like that of the half dwarfs & mainland burms. Which is to say they may be a bit defensive as very young juveniles - but that they also tend tamed down fairly quickly.
