Gearbox Identification

[redbarron]

Just wondering if anyone could confirm the identity of a 5 speed gearbox I have which I believe is from a R5 Gordini non turbo. It has the numbers 6.2 and 7700597823 stamped on the casing adjacent to the reversing light switch. The box was supplied as a spare with the purchase of a R5 Gordini non turbo. Any help much appreciated. I plan to sell it so if anyone is interested let me know.
Regards
Roger

There should be a sliver id disc on the box somewhere?
The numbers given don't seem to tie in to any specific box
All I can do find out at present for a 1223 Gordini is that it should be 385 or NG5 type depending on build date

id tag is on the end selector shaft case
