I have a 1957 2 door minor, and the air filter upon it is not covered in any manuals I have to date - If one of you out there could let me know if this is original/from what year etc and a parts list - looking for the rubber between the outlet and carb inlet to be particular. Any info much appreciated

Also - how can one tell if a Minor is a British home market or export model - I have been told mine is both by different people. I'm in NZ.[frame]
