Thank you for those mentions, Brian. The private labels are easy for me to forget!
Your recent comment in thread 45502 " ... If I remember correctly, the dates for the new features were: 1967 for Vanguard flat hood and box-top bag, 1969 for the Rugulator and 1971 for the Vibra Groomer brush roll." prompted me to revive this thread so as not to hi-jack that one.
Here's a timeline of features (and the first model-types of each) you mentioned plus some extras according to the print ads, VL posts and online videos I've seen. I continue to learn as I go, so it includes some updates from the "Chron-O-Matic" timeline. I included colors, as I recently learned that the colors of the Models 271 and 2070 were changed mid-production and to facilitate future clarification and identification:
1964—Stow-Away Tool Tray: "Princess" Model-Type 705-A, "Prince II" Model-Type 714-BV—both in 2-Tone Blue
1965—Cordaway: Model-Types 265-A in Lagoon Blue & Ivory, 1100-A "Empress" in ivory & green(?), 730-A in 2-Tone Blue & 745-A in 2-Tone Blue; 555-A in 2-Tone Blue
1965—Tool-Pak: Model-Type 730-A in 2-Tone Blue
1966 or 1967—Tapered Hood (like Thatwasherguy's), likely coincided with Hoover's square hood introduced in 1966: Model-Types 266-A; 270-A/271-A w/Cordaway—all in Lagoon Blue & Ivory
1969—Box-Top Bag: Model-Types 270-B/271-B "Custom"; 2080-A/2081-A "Vanguard"—all in Moss Green & Fawn Beige w/Cordaways
1969—Rugulator: Model-Types 2080-A/2081-A "Vanguard" in Moss Green & Fawn Beige; 2070-A/2071-A in Lagoon Blue & Ivory
1969—Dial-A-Nap: Model-Types 2010-A/2011-A, 2020-A/2021-A—in 2-Tone Blue; 2040-A/2041-A, & 2050-A/2051-A—in Lagoon Blue & Ivory
1971—Vibra-Groomer: Model-Types 2070-B in Lagoon Blue & Ivory & 2080-B "Vanguard" in Moss Green & Fawn Beige
1972—Disturbulator w/Beater Bars: Model-Types 238-FB, 2010-RBT, 2012-A, 2022-A, 2032-A, 2044-RB—all in Moss Green & Fawn Beige; Power Team Roto-Matic Model-Types: 1260-A in Rallye Gold & Cream, 1265-A in Big Bad Orange & Cream, 1285-A in 2-Tone Misty Green
