Hi Paul.
To be honest I'm not up to speed with griffon boxes...
What I do know is that the early ones had Albion gears, the other gear manufacturers were PGT, the most sort after boxes are the jack knight ones, then I think the mk2 griffons gears were manufactured by Quaife.
There are also different gear sets, Close Ratio, Wide and intermediate Wide Ratio
Geoff Nunn would happily tell you but is not on the internet/computer..
Oh and early Griffons had a 5 spline clutch, the later 6 spline.

GB1 is a close ratio Albion box.
GB2 is an intermediate wide Albion box.
GB2C is a close ratio late PGT or Jack Knight box,
GB3 is a very wide Albion box.
To be sure what you have the only answer is to take it apart and look at the gears.
There are three manufacturers, 2 tooth forms (12DP and 10/12 DP) and 3 normal ratios (18 combinations?) although it is possible to get different ratios by playing with the individual gears.
