    I've been wanting a BA set for some time and this was only £20 off eBay! Sizes are 10BA to 0BA, plus there were a few extra taps, BSW mainly. This should prove very useful!

    @ColinG

    Are you sure you haven’t been sneaking into my shed...? I’d better go and check.;)

    That is a nice kit.

    Cheers

    Yup, it should be very useful as so many British lamps use BA sizes, Willis and Bates being just one.

    What set to search for if one want a set for the Swedish lanterns?

    I haven't got a clue what type they have.

    Any ideas what to search for?

    Swedish lamps use a combination of Whitworth and metric threads. When you think of Primus, they made their own. Usually metric diameter with Whitworth thread.

    @Nils Stephenson ..Do you mean a metric thread with a Whitworth profile?

    ...Or that the thread length corresponds to Whitworth T.P.I, but the diameter is a metric size?

    @Tony Press , @podbros
    An example is the Primus 1020 jet. the Thread has a 7mm diameter but it uses a 35tpi Whitworth thread profile. Primus was part of the huge Bahco company, so they could make whatever they liked. This way you had to buy genuine spares. A good idea at the time, but not for us now.

    The problem is that a many of the concerned parts on most of the brands I've seen have non-standard dimensions on the threaded areas. Well the threaded pitches could be standard Whitworth, UNC, UNF/UNS or metric, etc but the diametres aren't. Which means that many couldn't be threaded with standard taps and dies.
    On such scenarios, I'd have them threaded on a lathe, which could produce the standard pitches on any diametres (outside threads). Threaded holes would be a little more challenging without the specific tap size.

    I remember having some problems with the 35tpi Whitworth on a Primus jet, which is not a standard size.
    35tpi is not a standard unified thread pitch as well. It couldn't be produced on a general purpose lathe too.

    Beautiful set. I remember using a tap and die set for the first time and how it revolutionized life in the shop.

    Pivotal moments in my life--learning to weld (still a hack), use a tap and die, use a sewing machine, fly cast without piling the line into the back of my head.

    Mike.

    I don't know which tools you'd need for Swedish lanterns but almost certainly metric.

    Thanks all for the response. I'll search for a set for metric system.
    So much knowledge here.

    I have a metric set and a Whitworth set. That covers a lot of applications. For some reason Whitworth was very popular in Sweden in (at least) the first half of the 1900s.

    Just a few more examples. The screw for the top nut on Primus hoods is 3/16" W, the nut holding the cage base to the tank is 1/4" W and the grub screw for the cleaning wheel is 1/8" W.
