Roco curved turnouts question

[Anonymous]

I'm working from a plan reprinted from a Model Railroader issue from at least 10 years ago. It calls for a set of Roco 42368 remote curved turnouts (L & R pair). My local shop looked at me like I had 2 heads when I asked for this, and they had no clue what these were. From the plans, they're turnouts in which both the main line and the turnout are curved (as opposed to the usual in which the main is straight). Does anyone have any info on this, or a substitute (I definitely need both lines to be curved in order to fit the space).
Thanks!
