    How old?

    Just a thought, you may be able to age the gun [ish?] by the threads on the screws if they are metric then I would guess post 1965? if they are BSW / BSF or some obscure size then I would guess earlier. kind regards Al.

    PS. but I do know that old stock of imperial fasteners was 'used up' for many years after metric was adopted?
    PPS. Have looked on Garvin's excellent site & I now think it has been soft solder together & what about those square nut's ! so now I think mid 1920's early 1930's?

    You could be right as they are very neat joints, but I am puzzled that the filler seems to be as rusty as the rest of the gun. It could be down to poor colour rendering in the images of course, but I would have expected soft solder to age to a grey rather than brown

    I think - perhaps? 'old soft solder' would have not just lead & tin but also arsenic & other elements ? mercury? etc.

    Bloody Hell ! I should have been a pathologist

    The 'Ripple effect ' those joint have would not normally appear on a soft soldered joint unless it did not get hot enough to flow correctly?

    Soft ( Lead based) solder will scratch easily with a pin or needle. Hard (silver) solder or braze will not

    Like a wheel roller your thinking.
    Possibly!
    Based on the info received so far it would seem that this was made a good few years ago, on the items paired together.
    If that method of welding was popular at that time i guess it cant be ruled out!
