I'm trying to decide where the main wales go and finally decided that the area between indicated lines (the two red arrows) seems to be the spot. can i get a couple of confirmations?
There is also a contemporary cross section drawing existing, here the wales are clearly visible and you can compare this with your longitudinal drawing
Thanks guys. I do have the cross section drawing but since it was just showing the dead flat it helped but didn't show the entire length and left a little room for doubt. It is surprising how much is showing on these minimal drawings. Sometimes you just have to stare at them for a while.
Onward and upward
