INSTRUCTIONS FOR ORDERING
To simplify ordering of parts, exploded views of the various sections of the
mechanism are shown in the same illustration as the assembly of those parts. On
the page opposite the illustration is a list of parts with key or reference numbers
to indicate the position of that part in the illustration. These key numbers in the
first column are for reference only and are not to be used in ordering parts.
In ordering from this list, use ONLY the PART number in the SECOND
column.
The number stamped on a Sewing Machine Part is the number of the single
part only.
Every combination of parts sent out has its specific number which, although
not stamped on Parts must be used when ordering the combination.
Each number always indicates the SAME PART in whatever list it appears,
or for whatever Machine.
The letters after some of the numbers indicate the style of finish only, as
follows:
AL Heat Treated for Toughness.
C Hardened only.
D Polished only.
E Soft, Not polished.
F Hardened and Polished.
H Blued.
J
Nickel Plated only.
K Hardened and Nickel Plated.
R Phosphate Coating Formed on Surface of Iron or Steel.
W Polished and Nickel Plated.
These letters MUST BE USED when they appear in the list and AFTER the
number, as in the list.
