Hi Michael, although I have not seen one 'in the flesh', the Rover 45 Owners Manual (in the Parts Lists and Manuals area of the forum) states "Rover 45 Owners Manual...Models 45048 and 45148.... and pictures contained therein confirm an 8 bladed machine, which would indicate a 20" machine.
The manual is dated November 2005.
It would appear that the 14" mower was discontinued. wink
