There are 4 photos of the item below. Included are two original Hewlett Packard Model 410B Vacumm Tube Voltmeter manuals. One indicates it is for serial 8355 and above and the other for serial 16334 and above (has a tear on the front cover at top edge). Both are dated 1955. Contents appear excellent with some natural cover wear from use.
