Peter,

What a great mystery to solve.  Based on reading your note and the replies of 
others  it seems like it is a TR4.  I have a '62 TR4 with a '66 TR4A engine, 
gearbox and other bits here and there... but there is no way to confuse the 
two cars after even a cursory inspection.

I will reply in the of your note if I can add anything to the already advice 
you have received.

The Piggott book is the bible for originality.  the TRA (Triumph Register of 
America) Judging Book is evem better.  But this is not a big mystery unless 
some put a 63 body tub on a 65 TR4A chassis... or something like that.

My TR4A engine in 66xxx series has HS6 carbs but in every other way looks like 
a 62 engine with the open breather.  Only a real TR4 freak can tell the 
differences.  This was a common thing to do 20 years ago instead of an engine 
rebuild...  take a low mileage engine and gearbox out of a wreck TR4A.

Not that I know of.  Why don't you buy a new blank plate from TRF or Moss... 
get the BMHIT to find the correct CT number... stamp in the correct number and 
rivet it into the car.  When I refurbished and cleaned my engine bay... my 
commission number plate was all beat up and stripped of black paint.  Just for 
cosmetic reasons I made up a new plate and had riveted into the body.  No big 
deal.

This means that the chassis is a TR4... the handbrake is drastically different 
on a TR4A.  So TR4 body and chassis...  I'd say it was very like a 1963 TR4.

My car came from NY and CA before that.  It had a blue STC 63 aluminum tag on 
the body next to the commission plate.  This STC is "Standard Triumph Corp" 
and was a way of marking a car in some states, like CA, as to "model year"  
when Triumph really did not make a distinction.

Hope this helps.  My website is full of TR4 pictures in the bare and finished.
 Check it out.  I would be happy to help you with any questions.  It's great 
to have another TR4 on the list.
