Hi Ken, The prior owner told me that it originally came with carpet and that she replaced it. There is no doubt now that it had been originally made with the carpet in place. Uwe recommended that I check in the deep dark sections to see if the carpet was there, too. We have torn it apart to verify that the carpet was under all the cabinetry. See attached photos.
There is carpet under all of the cabinets, lining the wheel wells, etc. We also checked with carpet folks and the carpet in there (not the berber that the prior owner of 40 years installed later) was period correct.
Although I am new to AS's, I have significant experience with coachbuilt cars and the research associated with it. It seems clear. Who would have thought?
I really appreciate all the help that I have received from the AS folks. I'll work on the Coronado Mfg lights. Those are buggers and I need all four!!! I guess adapting a generic will work. Thanks again!
