I have gotten out the original drawing of the above rearrangement. I can add
a bit more, but probably not everything.
a. 3R is normal from the base to 100A where it is capped with the tip of the X
(1-3)
b. the tip of 3L (61-64 sticks out of the chromocenter and it is unclear what
it is attached to. The cell has a split chromocenter and the base of the 4 can
be seen in the part of the chromocenter into which the 3L tip is inserted. It
could be the 3L tip caps the 4th.
c. The X is normal from the base to salivary region 3 where a piece of 3L is
attached and this is inturn capped with most of the 4th.
d. Which part of 3L is on the X is not completely clear from the drawing. I
have 3L normal and paired with its homologue from the base to 70/71 where the
rearranged 3L is capped with the tip of 3R (100F-A). There is then an unpaired
segment of the normal 3L and it then becomes paired again as it synapses with
the piece of 3L that is attached to the X. Putting this together I would
infer that it is the region 70/71-64 of 3L that is attached to the X. However
the label says 64-67. From looking at the drawing it looks like it may be a
piece about 64-67 in size from the X/3L/4tip piece that was paired with the
normal 3rd and there is then an asynnapsed piece that somehow didn't get
accounted for that could correspond to 67-71.
So my best guess is:
4th/64-70 or 71/3-20cc
100F-A/70 or 71-80cc
61-64/cc (4 base by inferrence)
1-3/100A-81cc
