ooops! In the above post I used the term "suffix" when I ment "prefix". Thus, my sentence above should have read:
"However, the engine has the prefix "TS" which denotes a TR3 engine -- the TR4 engines have the prefix "CT". "
The SUFFIX refers of course to the letters at the end of the engine number. On Triumph engines the suffix for engines sent to Morgan was "ME". For Triumph engines used in Triumph cars the suffix as simply "E".
If Hill says that 4840's engine was 2537HR, this would not seem to fit the regular Triumph numbering system. Was this a Lawrencetune number?
