I did look at the cataract bed last night, and
indeed the right side was stamped with the
obround hardinge logo, and underneath that was
a serial number, preceeded with the typical
N_o. stamp. The end of the bed had been quite
battered in its former life so that made it
tough to recognize, but the number is probably
2702 but there is a slight possiblity it is
2792 instead.

Because the numbers were stamped by hand there
is a fair bit of vertical displacement in the
digits.

If *all* the serial numbers are preceeded by
that N_o stamp then the headstock for this
machine is serial number 182. But it does not
have the 5-9 stamp there the way the others
do. Maybe that convention took a while to
catch on?
