PGB BME Posted December 18, 2021 Report Share Posted December 18, 2021 Does anyone know if there is a difference between the TR2 / TR3 small mouth nose cone Im told there is? But I’m not sure what the difference is? Phil Quote Link to post Share on other sites
AJ2014 Posted December 18, 2021 Report Share Posted December 18, 2021 (edited) Hi Phil, Yes there is a difference between the early TR2 small mouth apron and the later small mouth apron fitted to TR3. Below pic1 is the early one with a complete 4 sided tunnel from the mouth directing all the cool air to the radiator. Pic 2&3. The later one has the top of the mouth tunnel cut away ‘left and right’ to allow air to also travel up into the engine bay. Engine cooling was an issue on early cars. Somebody may have some better pics.. Regards Ade Edited December 18, 2021 by AJ2014 Corrected some text Quote Link to post Share on other sites
PGB BME Posted December 18, 2021 Author Report Share Posted December 18, 2021 Ade Many thanks for the reply my TR2 is a long door, Oct “54” so a later one, it has the 4 slot bonnet but the cut away nose cone does this mean the nose cone has been replaced or could it be a cone from the start of TR3? Does it matter any? Phil Quote Link to post Share on other sites
AJ2014 Posted December 18, 2021 Report Share Posted December 18, 2021 Phil Your car being early it would have originally had an early front apron like my first picture. It only really matters if you are building a concourse car. I’m sure a lot of owners would have modified their early small mouth apron or changed it to the TR3a wide mouth like my car was, in order to gain better cooling and also look like the newer model. Bonnets are complicated as there were at least 7 varieties according to Bill P’s book. All bonnets had 4 slots up until TS6157 when it changed to 2 slots Regards Ade Quote Link to post Share on other sites

Phil More than likely a TR3 one, you can tell by looking for the holes to fix the reveal moulding which on later TR2 went part way round the mouth so there are no holes along the top of the mouth unlike the TR3 where it went all the way round.

Stuart. Grille trim variations between a 2 and a 3 is the other way round isn't it Stuart? Happy to be corrected but photos attached are how I believe the trims would be.

John McCormack Posted December 20, 2021 Report Share Posted December 20, 2021 Earlier TR2s did not have the chrome trim surround. It came in after my short door TR2 TS5038O. A long door car will have the full cowling around the air inlet and no holes for the chrome surround. If it has the open top inlet and holes it is a TR3 apron. If it doesn't have the holes for the surround it is likely to be a TR2 one modified later but I would expect such a modification to be poorly done. There is no advantage to opening the inlet, it reduces the air going through the radiator for no real benefit of air going over the radiator. Quote Link to post Share on other sites
