    I got my first 42 ( Link ) some 3 years ago, and liked it so much that I decided to buy additional 42's. I recently found two nice 42's on eBay France, and bought them both. This Radius 42 is the first of the two (I will post the other in a few days). It was in very good condition, and lit up right out of the box. (I did replace the filler cap seal as a precaution, because a leaking seal UNDER THE STOVE is a risk I would not take.)

    Starting, as is my custom, with a couple of flame shots:

    1369858123-IMG_6204.JPG

    This stove has a bottom filler cap, and no SRV. The writing on the side of the tank shows "Radius Ltd." as the trade mark. There is no shooting star logo. This places the manufacturing time after 1938 (addition of Ltd).

    The tin has the two loops for the light and burner attachments.

    My first Radius 42 has a shooting star logo on the side of the tank, and no "Ltd." in the trade mark, suggesting it is earlier than this one (probably pre 1932). It also has a bottom filler cap, but it does have an SRV on top. This makes me wonder why Radius decided to do away with the SRV. Intuitively I thought that the no-SRV model would be earlier than the one with the SRV, but the data suggests otherwise.

    When I got the stove the tin had almost no scorching on the paint, which is quite unusual for this model. As soon as I lit the stove, the paint on the rear top of the tin started smoking, so I shut it off before there was too much scorching. I then realized that the scorched paint is the result of a design defect of the tin. The burner sits below the rim of the tin, and the pot sits directly on the rim of the tin, allowing no air gap in between. This probably increases the heating efficiency of the stove, at he cost of burnt paint and probably more CO emissions than similar models. I found out that both the Optimus 80 and Primus 71 tins have raised pot rests, which places most of the flame above the rim of the tins.

    Here are some more photos. I ran the "tea test" with my mesh pot rest / windscreen, to avoid further scorching of the paint.

    Hi Yonadav.

    I'm also a fan of the 42 and acquired another last week. It came in an orange and blue case that I've not seen before. I'll post some pics when I've sorted the stove.

    Like you, I'm unclear as to the production sequence of the 42. I've now got three and none are identical. Once I've sorted the latest one I'll start a thread showing all three and hopefully other owners will add theirs which may help us get a better understanding.

    Regards,
    Terry

    Questions:

    1. Is my conclusion correct, that the model without an SRV is newer than the model with the SRV?

    2. If so, can anybody suggest a probable reason why the SRV was eliminated? (and then restored on even newer models?)

    3. Does anybody know when Radius introduced the newer tin design with the raised pot supports?

    4. What is the purpose of the loop holder in the top cover of this tin?

    I can answer # 4 for you.

    The Radius 43 came with a bunch of adapters, a blowtorch head, ski waxing head, and a lantern attachment.

    I've got one here, less box and control key, rather anemic flame, compaired to a 8R or 99, If I can find a No. 7 stove box, I'd get one and see if it worked better, haven't seen one about lately.

    Just nicked a valve key for a Primus 71 off fleabay, hopefully it will work with the Radius 42

    SUCCESS!!! :clap: :clap: :clap:

    The valve key from a Primus 71 works perfectly with the Radius 42! :thumbup: :thumbup:

    Now, to find a Army No.7 box to go with it, and I'll be a happy man (well, for a while).
