Ted, If your E38 was built anything like our E31's were, I can tell you for a certainty that many features of these boats were offered as options, that teak cap rail being one of them. The final configuration of an E31 as it exited the factory doors was strictly a function of the depth of the pockets of the original buyer. I have detailed records to back up my assertion that there were no two E31's built alike and it could be that your boat was treated the same way with options requested by the first owner. It might be fun for you to visit other E38 owners and their boats to compare notes and see what other options your boat or their boat have. I suspect that you'll be very surprized. Regards, Glyn
