Whilet I am familiar with the vehicle#, body#, engine# etc. on our Triumphs, I have never seen a plate quite like this one. http://www.flickr.com/photos/keithchristr6/sets/72157635192324690/ It is on an early TR4 (November 1961) CT1218LO. Has anyone come across such a plate and what does the information mean? Keith Stewart keithstewart at execulink.com
