Repost of the annotated clip of the SE spout of f86v3, "The T-O Map". This time with more annotations, including one case of imperfect retracing (F) and one good example of normal weight variation due to ink flow dynamics (S1-S8).
This clip covers the distal half of the big "spout" rooted at the SE corner, including the bird nest and "stadium lights". The clip is rotated 90 degrees clockwise relative to the normal reading orientation of the page.
(A) Presumed original (Rt0) traces. (B) Presumed Rt0 traces. Note that they cross the Rt1 outline of the "nest". (C,E) Presumed Rt0 outline of sprout. (D) Rt0 ribs of the sprout. (F) Rt0 trace of scallop, imperfectly retraced by Rt1 as (S7). (G) Bit of Rt0 (or maybe Rt1) not retraced by Rt2.
(I) Edge of nest is Rt1, may not follow Rt0. (J) This part of bird may have been mangled by Rt1 and/or Rt2. Note the feathers of the wing crossing the outline of the nest, the backside of the bird in front of the wing, the doubly-traced hump, and the incongruous interaction between the upper filaments lines (A) and the edge of the nest, See inset for possible original. (K) There is no Rt0 trace of these "stadium lamps"; they may have been added by Rt1.
(Q) These circles are possibly Rt2. ® Outline of the base of the spout by Rt2. No Rt0 trace is visible; it may be an Rt2 addition. The nebuly edge at NW, in particular, may have been created as the outline of the hatch lines above it.
(S1-S8) Example of ink flow dynamics. The Rt2 scribe started retracing these scallops from (S1) to (S2), tracing each scallop in the CCW sense. He continued at (S3) and proceded up, row by row, right to left in each row. At (S4) the pen began to run dry, but he continued in the next row from (S5) to (S6). At that point he recharged the pen with ink and finished with scallops (S7) to (S8).
