Enablers you all are... I got my ebay Ken pipe today. Just because. I couldn't resist a pipe for 7 dollars, oddball like me and named like me. :D
The bowl is in good shape, should clean up OK. The oddity innards are rather sad though. I did get the thing taken apart. The patent shows all the parts, including the leather washer and wood screws! I cleaned the stem (it is lucite) with scrubbing bubbles, which loosened all the crap without etching the stem. The 'bubbles' do eat hands though. I will use gloves next time.
My pipe has a nice amber colored stem. I will clean it up and repair it, but probably will just leave out the odd 'condenser'. I may install a new longer draft tube since the piece in the bowl of mine is broken. It is just a simple aluminum tube. Might use stainless as a replacement.
I will start a new thread when we get our house move over and I have time to finish the repair.
Mine is made like the patent drawing, only one 'bell'. The screws actually came right out. The retaining washer under the screw heads is broken in half, so I will need to machine a replacement when I get my lathe set up.
