This RGA head came from a lot of surplus equipment I bought along with a turbomolecular pump, pressure converter, and a bunch of other fittings.  I don't have the means or expertise to test it beyond visual inspection - it appears to be operational (no broken lines, insulators, grids, etc.) so I am selling this as is.  The filament is in tact, which is probably the most delicate part of these instruments.  Judging from the condition of the turbo, which I do have the equipment and expertise to inspect thoroughly, this came from a home where it was well serviced and cared for.  It is leak tight to low 10^-9 Torr.  I didn't try to go further because the helium leak checker doesn't .   You can't really make anything out on the label except for the Inficon Leybold Heraeus name - the text that was printed on the label is faded, but I sent pictures to a rep at Inficon, and he says it is one of their IQ200 heads.  The controller and electronics are on ebay regularly for this unit, so you can piece together a quality instrument for thousands less than the cost of a new one. Ask questions if you have them.  I'll do my best to respond quickly
