Using alt _N_ and _R_

Image is too small for me to make a 100% identification, but note that Leo Condernsed Bold is Bay Animation's Version of Libra

Custom Lettering. Anne Occi - Major League Baseball Design Services Division
The look and feel of the lettering were adapted from Flange. There was a lot of editing.

Thunderbird digitally compressed 40% in width looks like this:

Looks like this is the source of the painted lettering which is made a little heavier and has some minor simplification
P.S.
The compression should be more than 40% but I am not going to bother repeating the exercise to get the closer match.

Is similar, but it is not the font

Higher definition image of the logo


Standard fonts do not have letters where the top or bottom is expanded or contracted to fit an arc as used for _MOTOR CYCLES_ in the logo.
After adjusting the letters to make them the same height a result could look like



or a similar result a little taller or shorter.
This is a good match for Forgotten Futurist Bold, currently offered at no charge at Myfonts.

Forgotten Futurist Bold is also offered here at Dafont

Perhaps the signmaker's letters were indeed inspired at least in part by Lucida Calligraphy, but there are significant differences.
Another possible source of inspiration might be Arioso. Note that this is NOT THE FONT

Handmade sign.
Might have been inspired by Lonestar -- NOT THE FONT -- which could be modified to make a substitute for the letters.

Preciosa with the lower case of small caps edited to strip away the ornamentation

Ravenscroft

Hoefler's Didot 16 Bold
or perhaps Hoefler's Didot 24 Bold.
The hairlines in Didot 24 are thinner than Didot 16.
Need a higher definition image to say which one

Duc de Berry with edited _G_ and custom _T_

Ravenscroft edited to paste the lower rhs terminal of the lower case _k_ on _K_, and paste regular terminals over the fancy ones at the bottom of _M_ and _N_.

This is not a stencil font -- the counter on _a_ is not cut. TT Squares is edited with some cuts -- presumably to create a chopped effect -- that make no sense if a stencil is intended

EDITED:
Even if we find a matching .SHX font, converting it to an otf/ttf/pfb is not a walk in the park.
The fonts in the pdf seem to have been converted from .SHX to .eps, which is a format easy to extract with Illustrator and copy to Fontlab for editing.

@speters33w:
I looked at the Hershey Fonts but they have me stumped.
They have no extension in the download to suggest what format they might have.
There is a download for PC with a .fnt extension but the fonts are unrecognized as valid fnt files by FontForge and by online converters such as http://www.files-conversion.com/font/fnt

Might do better to find a substitute among the various Leroy Lettering or DIN fonts that are available in otf/ttf/pfb

Informative answer
The pdf document contains vector paths taken from the instructions for routing machines.
The vector paths can be made into computer fonts by importing them into a program like Fontlab and giving them width by using a parallel line technique.
Unfortunately, it takes some skill and experience to make a matching computer font from a no-width vector path
Perhaps somebody has already done this for "NORMAL"
