I reckon it's a 1995 or 96. You should be able to decode it from the frame number.
1995 officially in the catalogue was without the canti boss on the rear, although some early ones that year still had it, even with a 95 date code.
Checking headset diameter is a good idea too, I cannot recall when it went from 1" to 1 1/8", maybe 1997.
Have a look in the catalogue section:

Note that not all the info Orange gave out is right, for example on seatpost sizes.
