john:   the discussion has been about the M15.   a quote below from jerryM     dave scobie M15 #288 - SCRED visit Scred's www-site: http://www.freewebs.com/m15-named-sced     quoting jerryM-   jerry@jerrymontgomery.org   I think this is all documented in the archives.  I originally tooled the 15 for an exact fit for the PP35.  vA few years later Thetford dropped the 35, replacing it with the 135. I bought all the 35's that I could find in the pipeline, and when they ran out I retooled the mold to fit the 135. I have fit 135's to the 35 bases using a hair dryer, and others have done it using hot water.  In both cases patience and a beer in hand are helpful. jerry --- On Tue, 4/21/09, John Ledger <johnledger@aoi.org> wrote: Does anyone know if this method works for a M15?
