Sorry chaps if that seemed rude of me;I can`t get the link to work now ,but `google `dryden flight research centre`,then go `phot gallery`,then scroll for X-1, and it should have a `thumbnail` selection,and choice of resolution;clicking on that cockpit pic in hi/large should show the altimeters in top lh side of the instr.panel,as you say E49-00010.jpg; one 3-pointer normal altimeter,which,may only have gone to 50000ft,as there was nothing else capable,and then a single pointer which starts at 53k and goes to 140k .Maybe someone can down/upload it..Syc
