    Came across this Taiwan clone 99 on the right and it has flat alloy heat shield. Both my made in Sweden 99's have chrome heat 8R style shields . I see other made in Sweden 99's with flat alloy heat shield too. I did a search and found out the 99 did not have many changes during its run but this was one of them . Thought I would share this.

    Are they all attached to the case bottom by a screw?

    Yes, single screw holds burner in the case. Even has small indent to keep tank from resting on case when in very cold conditions. The 99's with chrome/nickle 8R style shield are the older ones. Read about them this morning some posts go back 15 yr I think the latest was 2015. Daryl

    HI, @Daryl ,

    if I may offer a small correction: The flat aluminum heatshield was the original design of the 99. Please look at this 1976 catalog to see the proof:

    https://classiccampstoves.com/threads/1976-optimus-catalogue.9220/

    And, here's another look, from an early 1980's catalog:

    It wasn't until the 99 was on it's last legs, that Optimus began supplying them with the 8R type heat shield. Just thought you'd like to know. I have quite a few early 99's, and all of them have the flat, aluminum heatshield. I have only a few of the later types, with the 8R type of heatshield. Thanks for sharing your collection of these! Take care, and God Bless!

    Doc

    @Doc Mark Thanks for the correction and sharing. Sorry I got it backwards. I do remember reading your posts from some 15 yrs back about the two type of heat shields. Until this week I did not know 99's came with two different shields. I just picked up this clone this past weekend and thought the flat shield was to cut costs. Did a little searching on this site a saw others with flat shields.
    Curved or flat both are great little stoves. Stay safe

    This thread has reminded me I picked up a 99 not so long ago on a local online auction and I've yet to make time to test it.

    I just lifted it up, turned it over and confirmed it has the bottom screw pictured above, on the bottom.

    I think its missing the screws that hold, in my case, the aluminium heat shield (to the case and not the tank)
