Disk drive mounting rails for AT&T 6310, 6312 PCs

[Andy Perch]

I am looking for a source for the kind of disk drive mounting rails
used in AT&T PCs, particularly for the 6310 and 6312.  I have called a
number of AT&T information lines and it seems the rails are not
available.  If anyone has a part number and comcode for AT&T's
version, or a lead on another source such as Olivetti, I would
appreciate hearing about it.

Thanks,
Andy
