You posted some fantastic bikes...but this is my fave so far. The bars being a big reason. Most bmx cruisers/strandies/klunkers/etc have pretty low bars, but I like running 8.5" to 10" bars on mine as it not only 'feels' better (comfort and control) to me...but it takes me back to being a kid on a bmx bike that feels big.
Those CW(-style) bars look great on that Littlejohn, and I bet they feel great too ,
They were so popular for a while, that there were many, many, copies. As far as I know the only way to get a good idea is to weigh them (CW used thin-thinwall cromo) and diamond knurling as opposed to straight knurling.
Jason (not a brand snob...but, definitely a bit of a cromo snob with weight weenie tendencies )
