Here is the taper for the Model #17, 1 1/2F Extra Lite Trout rod.  This
casts well with a #3     333 DT line.  Also tried an F silk level line
that casts well.  1 1/2 F (16/64) butt ferrule, 10/64 tip ferrule.
Black tenite (3 1/2") downlocking reel seat.  Pyralin butt cap.  N/S
hardware.  5 1/2" reverse wells cork grip.  Same pattern as the Model 50
President, only smaller.  Black wraps with orange tipping.  All
measurements taken with 1/2" Starret mic using pressure release.  All
varnish was removed.  Mesurements taken with rod assembled, from the
tip.  Odd measurements are at the ferrules.  Tips are mirrored and so
little difference between the two tips I am only showing one
measurement.  Looking under a magnifier, this looks to be a well made
rod, all strips are perfect.  Used all three dimensions and averaged,
but did not find and great differential between the flats.  Nothing more
than .001.
