Not likely to be 7 and 9mm Allen keys - they're rare to say the least.
Try getting hold of an imperial set - shouldn't cost much. Maybe 1/4 or 9/32 for the smaller one, something like 11/32 for the bigger one.
( I'm SE if you want to borrow, but to be honest, for the cost it's worth having your own if you're keeping this stem.)

Cheers jsabine, dropped by the hardware shop in camberwell last night and they have a big set of imperial and metric Allen keys that includes a 7mm for £6.
Like you said its worth buying the set so I can keep the stem so ill pop back today and buy one.
Cheers.
I brought an old bertin frame yesterday with a lovely lugged stem that seems to need odd size Allen keys.
There are two holes in the stem bolt, I've tried a 6mm in the smaller one and an 8 in the largest and neither seem to fit properly so I reckon 7mm or 9mm will do the trick.
If anyone's got one I could borrow for a little bit that would be rad.
Preferably SE.
Cheers.
