QUOTE=Clandestino;2903149]Reason is severly banal... insufficient clearence between PL2 and CL1, which was easier to correct by cutting off half an inch of PL2 handgrip than by repositioning PLs and redesigning the entire throttle quadrant. In other words, originally there was no room for F/O's LH thumb.
Thanks for that Clandestino... seems like the best suggestion so far. I was kinda thinking that is was possibly some kit left over from a previous design etc.
