HAHA Lester, Not quite yet, pleanty of time for that
The barlow was made up of several different bits, the main tube where the EP or camera goes into is actually from an old barlow I had which I dropped and smashed the lens assembly. The bottom bit where the lens is is from an old 25mm Eyepiece that came with my TAL-1, (same with the barlow). The Lens assembly came from a stripped down 210mm zoom lens for a camera. All held together with good old electrical tape.
