MG MG Farina Magnette - Dating Triplex Glass
|
|
| Chris Roop passed this on over on another MG BBS and I felt you folks would like to know this info too. However, this does not apply to current Pilkington/Triplex glass. TRIPLEX DATE CODING MG's made in the 1950's to the late 1970's can be dated by the 'TRIPLEX CODE' etched into the toughened glass. My 75 GT has Sicursive side glass but a Triplex heated back-light with a code that fits the date of build of the car. This also works for any other make using TRIPLEX glass. Note that it dates the GLASS, so is only an indication of the cars age, assuming the glass is original. If you are not quite sure of the year of your car, but the decade is known, just look for two dots in the TRIPLEX logo on the glass. One dot above T, R, E, or X gives the quarter of the year the glass was manufactured: T = Jan, Feb, March, R = April, May, June, E = July Aug, Sept, X = Oct, Nov, Dec. but which year? Nine letters make the word TOUGHENED, one dot below a letter gives the year of the decade: T = 1 O = 2 U = 3 and so on. However, if you see no dot, the year is zero. Say your car is a 1950's MG, then TRiplEX TOUGHENED, with one dot over the 'R' in Triplex, and the other under the last 'E' in Toughened, indicates 'April/May/June 1958'. |

| Looks very like an article I wrote for the Morris Minor Club back in 1984, and repeated a few years ago in the MG Octagon Car Club magazine.... Neil. |
