I picked this old pipe up in a lot of pipes that was given to me. The pipe is stamped LHS in a Diamond and next to that SEC on the left side of the shank. The right side of the shank is stamped US Patent 1908630 over Other Patent Applied For. I have hunted through the patent information site and could find the original LHS patent under the number above but the descriptions and diagram do not match the system in this pipe. The stem is Perspex I believe, and has the cross hatched metal end on it. That is threaded and connects to a threaded tenon that is connected to the bowl. When I got the pipe out of the box of pipes it was dirty and the rim had a lot of tar. The bowl was not badly caked but had remnants of tobacco left in it. The stem was dirty and opaque. The internal filtering system was black with tars. The stem also had some crazing in it – this happens when alcohol is used on Perspex stems.

I reamed and cleaned the bowl of the pipe and the rim and then scrubbed the exterior of the bowl with Murphy’s Oil Soap undiluted. I wanted to leave the original light finish without removing any of the stain so I carefully rubbed on the soap and wiped it off. The rim actually came clean very easily and the bowl was ready to go. I took apart the internal contraption and cleaned that with Isopropyl alcohol and also cleaned the shank with pipe cleaners, shank brush and Isopropyl. One the internals were clean I worked on the stem and cleaned it out with soapy water, pipe cleaners and cotton swabs. The finished pipe was then waxed with multiple coats of carnauba wax on my buffer and then polished with a soft flannel buff.

Anyone have any information on this pipe? It is an unusual piece of pipe history and I continue to hunt down information. Thanks for your help and thanks for looking.
