5510/6200
Bill, I was just lucky to find a nice 6200 from a friend, this is the reason because I switched from 5510.
In my opinion they are both the rarest BC, much more than 6538.
BTW, the right case serials range for 5510 is 362.xxx, also some 361.9xx have been seen ......... talking about number of pieces produced I guess only few hundreds, below 500.
