My latest find is this KL80 which I think is a fairly early (1940 ish?) one due to the vitreosil shade, the "pringle" style heat deflector and the enamel shade. The preheater cup looks like it is off a Vapalux. This is how it came through the post to me - wrapped in a layer of bubblewrap and a bin-bag Fortunately it arrived undamaged.
Now now Jeff I have heard you say many time never date a lamp buy the removable part but I do agree with you Kenny,,
Very good Kenny! You are correct of course and I assumed that the XN., control cock is complete, is it James? I have had Tilleys turn up which have the shallow control cock socket and the bottom half of the XN., control cock has been removed and it will then fit into the shallow socket. However, when that is done it's no longer a control cock, it's only a pricker control, Jeff.
