Anyone have an HP 524B/C/D counter? I picked up an HP 525A 10-100MHz frequency converter plugin recently, and am looking to send it to a good home for the cost of shipping. The setup with this plug-in is pictured here .

The unit is a tad dirty but it seems complete with all valves except the magic-eye tube which should be an easy replacement. If anyone in the group has a counter and needs the plugin, PM me!
