My '70E, #9110220257, came with case #911/01, 6200391. I know that a Kardex is the only way to be sure, but before investing the money for what is said to be an unreliable document, is this a likely match? The Red Book lists one of four ranges of E engine numbers as 6200001-6202476, but the line in which this is shown reads "6200001-6202476(911/04 Sporto)", as do an additional two of the other four other serial number ranges listed for the E. Additionally, the book lists two ranges that start "610XXXX" for the E. Doesn't the "1" designate T, or is that just for the chassis numbers? All of the engine numbers are shown with the serial numbers for the Reutter built cars. No engine numbers are listed with the Karmann chassis numbers.

All help appreciated!
