    As received, Optimus 8f.
    Missing flame spreader but otherwise good to go.
    The fuel line on this model has no hex nut, I can see some thread tape in the connection which indicates the lack of the nut makes it more difficult to tighten the fuel line. The fuel line is thicker than an 8r so I guess it can handle more torque when tightening.

    Chrome tank
    embossed case

    The second stove in the photos is a chrome tank 8r. The 8 has the small pole under the burner.

    Hi Mods

    I don't know why that small thumb nail of the 2 stoves is at the top of this, I can't see it when I do to edit. Doesn't really matter but it may be a glitch?

    Nice picking up a older stove in good condition, thanks for sharing.

    Very, very nice! I don't know about you but I like how the burner sits up off the stove tin. It may have a smaller priming cup, but that's ok. I still like it.

    Thanks TYD!

    Nice Stove. I really like the chrome tank. Have you had it running yet? Does it operate about the same as an 8R or is it stronger due to the larger feed tube?

    Just fired it up, 8f on the left, 8r on the right.
    The 8 only took a single prime (inside garage). Looks to run a bit rich but I have not tried to adjust the flame spreader as it was borrowed from another stove.

    I just noticed the "8" on the embossed case is not in the center, it is off set to leave spase for the "r" on an 8r. I guess this makes this one of the last 8's made, probably sold along side the 8r, or possibly the 8fr that I think the chrome tank 8r (above) was probably called when first sold).

    However I am not sure if all 8's had the fuel line coming out of the center of the tank (like this one does) or if some had off set fuel lines (like an 8'r).

    I just received an 8R that burned yellow on fire up. The flame spreader looked to be in the same position as my other 8R so I left and let it burn for at least a half hour. After that, the flame started to turn blue and stayed there. I was thinking that maybe the wick just had some residual old fuel in it and finally burned off with Coleman Fuel in the tank. Just a thought on the yellow flames.
