Antique Collection 1900's Precision Voltmeters

Background:

We sell equipment for the university sector. Whilst we typically deal with more modern equipment, every now and again we come across a unique lot of antique instruments.

This clearout from a prestigious redbrick university included 23 antique voltmeters, ammeters or wattmeters, of which thirteen were in beautiful solid wooden boxes.

We estimate the date of the meters to be mostly 1900-1910. One unit has a date written on the original insert sheet as 1902. 

Many of the units have testing / service sheets with the most recent servicing typically being 1935-1940.

The full list of antiques are as follows:

• V27 Precision Voltmeter in box
• W17 Precision Wattmeter (50A) in box
• A81 Precision Voltmeter in Box
• V51 Precision Voltmeter in Box
• W16 Precision Wattmeter 5A in box

• A11 Percision milli-volt and Ampermeter in box 
• V68 Precision Voltmeter (in box but box labelled 'V25)
• V77 Precision Voltmeter in box

• V84 - Empty Box only (feels empty by weight) - box is locked, no key.

• A89 Precision Ammeter - max 100mA
• V71 Precision Voltmeter - 
• A63 - Precision Ammeter

These are all in fantastic condition considering their age. Only one box is missing a hinge, and one still has it's original handle in tact.

Most include a service sheet or other insert sheets that are 70+ years old.

This is truly a rare and unique lot and viewing are highly recommend.
