P.R.D. (Pocket ? ) Voltmeter, out of the 1920 ??

[Dribbel]

From an attic clean up, I got an antique voltmeter, with ranges ( via
the test pins ) of 8 and 16 Volts.
R=250 ohms at 8 Volt range
R=5000 ohms at 160 Volt range

Questions:
- does P.R.D. stand for Deutsche ReichsPost, or an other meaning ??
- On the box is the Company sign of Normameter
- Was Normameter the supplier to the Deutsche ReichsPost ?
- Year of production ??
- Or: Does P.R.D. mean: Deutsches Reich Patent ??

Would any museum be interested ??

As a kid, I had one of those! Heavy, built like a battleship and worked
well! That could well have been mine, decades ago!

AFAIK that sign is the logo of Josef Neuberger, Fabrik Elektrischer
Messinstrumente in Munich. Normally Neuberger is written in small font
on the lower left of the dial.

- Year of production ??

Hard to say but I think they were still made in the 50's.

You could ask these guys but I bet they already got some because that
kind of meter used to be popular in Europe:

If it's written in the right sequence, it's "D.R.P.". This stands
for "Deutsches Reichspatent". So your second assumption (see below)
is right.

- On the box is the Company sign of Normameter
- Was Normameter the supplier to the Deutsche ReichsPost ?

I second Joerg: it's the Neuberger logo.

I'm sure that there are a lot of collectors who would like to
get it. Why not sell via eBay?

Hello,
My father (Belgium) had also such a meter. As said, it was a very
popular meter.
