[Boatanchors] Documentation for Triplett Model 1251 VTVM?

[William Morton]

Hello All,

A friend of mine sent a picture of a Triplett vacuum tube voltmeter, model 1251, he came across.  Looks pretty and I especially like the double meter on the unit.

Both he and I have searched the web for documentation and/or instructions but we were both unsuccessful.  Does anyone out there have a pdf of any documentation or a source of such?

Thank you all in advance for your help.

Best Regards,

William
