**Condition Notes (Please Read Closely Before Buying):**
This is a loose-leaf, 3-hole punched paper manual lot (pages have been separated from their original binder cover and will ship loose but neatly stacked, organized, and structurally protected).
* **Handwritten Notes:** Includes authentic vintage handwritten student field notes, distributor names, phone numbers, and addresses in the margins of a few pages (such as Lesson 5 & Lesson 6). All instructional text, diagrams, and schematics remain fully clear and readable.
* **Water Damage / Staining:** The rear pages of the manual show historic water exposure, resulting in visible brown staining, moisture rippling, and text bleeding/transfer on the back page margins.
* **Tears / Wear:** The back page has a torn out, blown-out bottom 3-hole punch ring as shown in the close-up photos. Front pages exhibit normal vintage edge tanning, small corner creases, and minor surface smudges from real-world garage and workshop use.
There are no missing text pages within this Lesson 1–8 run. Chief Instructor signature page is present on the final memo sheets. Missing the original outer binder cover shell.
This lot is sold exactly AS-IS, "what you see is what you get." Please carefully examine all high-resolution listing gallery photos to verify the exact condition details before finalizing your purchase. Ships fast and securely flat-packed via USPS Media Mail.
