Dear John and James,
I just checked at the SEM. The 0.9 mm allen key from one of your sets
you left at the SEM fits.
I put this one from you allen key set in the tweezer box and I left
the the other sets at the SEM.
We already used it for one SEM session this morning and will again
later in the evening today.
Thanks again for providing one so fast, John !
