JMCO (IMCO) Patent A (Ultimately Called the "JFA/IFA" Lighter Later)(1922)(2nd Version)
Edit: Date changed to 1922 for version 2.0 after finding a more accurate source)
Other than a theoretical 1918 version I've only seen one questionable photo of, I think this completes my "brass shell" set of early IMCO lighters. Some had different labels and some like this one were imported to the USA by MEB, but this is the 2nd "Patent A" design. It needed a good brass polish and a new wick, packing and flint.
The first one (pictured in the last photo below beside this one) had no sliding outer shell with vents and thus no wind protection option (you can have the wick behind the vents and thus protected from the wind by simply moving it down farther on the 2nd version onward through the 6th version), which the next iteration adds by using the inner cylinder/outer jacket system. The original 1st version had a sliding cap that was pulled upward and then down to light it.
The next (3rd) version (also dated 1926 by other sources, although I wonder if that's accurate...
EDIT: Another site says 1922, which makes more sense) moves to a smooth (not grooved) snuffer cap (probably cheaper to make?) and adds drill holes midway up the rotating shaft were a wire is attached to a hook on the back used to pull the snuffer off when you pull down on the ring on the bottom (semi-automatic operation). This version you have to pull the ring (inner cylinder) down and then manually move the snuffer away from the wick.
The 4th Version known as the JFA or IFA "Extra" switched to slanted vents. I assume they work better in wind since all the remaining versions use them. The 5th version (4000 "Streamline") squishes the body down to a more compact or "streamlined" shape. The 6th version switches to an octagonal body. I'm guessing this was deemed stronger or something to that effect, but I have no idea for certain.
Technically, the 5800 model is also labeled JFA/IFA and seems like a progression in the sense it retains a separate flint wheel, but it goes back to having to move the snuffer off (this time as a hinge in the opposite direction) and uses the 4700 Triplex's "button" style spring pop-up to access the flint tube. Its body is more similar to the Triplex (rounded cylinder with a bottom cap marked) and seems a hybrid of the two. These are pretty rare so I assume they didn't sell very many as it seems kind of a backwards progression compared to the Triplex, which sold exceedingly well and was later upgraded to the 6700 "Super" version that is still made today and has been since 1956!
Thus,
Prototype = No Cap in photo I've seen, but otherwise similar to 1920 version. Could be a 1920 without a cap for all I know (1918)
1st iteration = Fully Manual Operation With No Wind Protection (1920)
2nd iteration = Wind Protection Added (1922)
3rd iteration = ("IFA" or "JFA") Semi-Automatic operation with wire to pull down snuffer when pulling on bottom inner cylinder (1926)
4th iteration ("Extra") = slanted vents (no idea purpose)(1927)
5th iteration ("4000 Streamlined") = squished body to take up less space in a pocket and continues slanted vents (1934)
6th iteration ("4400" in Austria; "Buddy" in USA) = octagonal body (no idea purpose of this shape)(1936)
7th iteration ("5800" IFA/JFA) = Reverts to manual lid open in opposing direction but uses the 4700's spring pop-up flint loader) with a grooved base. It bears less resemblance body-wise to the brass cylinders of the previous versions, but since it's labeled IFA/JFA, I've included it in the list. (1947)
