    I’ve been pondering the bottom stamping of Canadian Coleman 118B lamps.

    I’m trying to understand any pattern.


    1. This lamp of @ROBBO55 is dated 8/37 (stamped on side of fount in the usual manner) and has the following base:

    Note: It has no model number. Has “CQ”
    stamped on the base.


    2. This lamp of mine dated 7/37 (stamped on side of fount in the usual manner) has the following base:

    IMG_0468.jpeg

    Note: It has no model number. Has “CQ”
    and “0” stamped on the base.

    3. This lamp of mine dated 12/35 (stamped on side of fount in the usual manner) has the following base:

    Note: It has no model number. Has “CQ”
    stamped on the base.


    4. This lamp (below) of mine is undated and has the following base:

    IMG_0457.jpeg

    Note: It has no model number. Has “CQ” and “1-0” stamped on the base.

    The lamp:

    The Coleman Book [International Coleman Collector’s Club (2015) Guide to Vintage Coleman Products 1900 - 1983, p.55] has the following text about the Canadian 118B:


    “Canada 118B/118BC

    Identification:

    Model number maybe stamped under fount as 118B or ink stamped.

    Instant lighting, gasoline, built in pump.

    Double mantle rated at 300 cp.

    Roto-Type burner - "generator with tip cleaning needle, operated by rotary lever built into burner".

    Stamped on side of fount with Coleman, Trademark inside Sunshine logo, The Sunshine of the Night, Made in Canada.

    Dates below logo, one or two digits on the left for month and two digits on right for year.

    Large, 8 inch diameter embossed brass fount. Fuel valve at base of handle.

    Bakelite valve wheel with direction disk.
    Smooth, wing-cap filler plug Parchment shade and mica protector sold separately.

    118B Finish: Cobalt nickel plated, ebony black handle.

    118BC Finish: Brushed coppertone, matching handle.

    Other:

    118B in nickel plate commonly called "Silver Duchess", but catalogs only state "Duchess" 118BC listed for export in 1934 catalog in Brushed Coppertone color only.

    Documentation on this model is limited.”



    I can’t make any sense out of the bottom stamping on these lamps above and none have the model number stamped.

    Cheers

    Coleman did use up surplus base plates on later lamps.

    Hi @Tony Press , just saw this topic and got no notification.
    Jeff is right on, Coleman used up everything including baseplate products. Sometimes lamp stamped baseplate were even repurposed for lanterns, example: stamped model M lamp on QL lantern.
    The guide is very useful for just general descriptions, with no ability to be edited later is not always accurate after printing.

    Thanks, @coleman54.

    I've no idea why you didn't get notified, as I had tagged you. A glitch in the universe, perhaps.

    It's the bits and pieces like this that may be useful for the Pressure Lamp Catalogue revisions.


    Cheers

    @coleman54

    On the last base plate above, is the “1 - 0” a date? (Jan 1930?).

    If so, is the “0” on the second base plate therefore an incomplete date?

    @Tony Press , my not being fluent in Toronto stamping practices of the day I would say you are probably correct with both.
