HG nvr seems 2 remove the perm stix b4 xferring the batch 1s to
SL
Yup, SBS8079Y is one of them. Used to have a masking tape written
'163' on it when it was still HGDEP 163 perm. After transferring
over to SLBP to become perm 105, SLBP re-wrote '105' over the '163'
on the masking tape 
Same for SBS8107A, from '165' re-wrote to '105'.
