Chris,

Given the date of the maps these likely are not lines of
equal depth at all, but instead are artistic ways of showing
bodies of water or their "edges". I would not code them as
such in the Relief fixed field nor include them in any kind
of 500 Relief note unless there is evidence elsewhere on the
map that the lines are there for the purpose of showing
depth.
