Default BT Cream Rotary 8746G "This is not a telephone"

Hi Everyone,

I was wondering if you could shed some light. I have a vintage rotary telephone, 8746G. DFM 83/2, in the middle of the dial there is a letter M and around it says "This is not a telephone", please see the photo for details.
Does anyone know what the M stand for, and why it says that it is not a telephone?
By the way, it works perfectly fine.
Thank you in advance for your time and expertise.
Sherden

Perhaps it was a warning that this was only an internal phone and did not connect to an exchange, what most people would think of as a "telephone"

I thought the M might refer to the Daily Mail, but the typeface isn't quite right.

Maybe an ironic reference to Nick's $3m work of art,
or maybe it's not a "telephone", in the sense it wasn't capable of making external calls in its original location.

PS I see Peter has already suggested that last point.
PPS Welcome to the forum Sherden!

My thoughts immediately went to "M" for "Magritte" (as in the Belgian surrealist artist René Magritte) and his famous image "The Treachery of Images", depicting a tobacco pipe with the words "Ceci n'est pas une pipe" ("This is not a pipe").

I must also say that the image by Miguel Vallinas linked to earlier does have something of a Magritte-inspired look about it as a stepping stone between the two.

Turning to the telephone itself, I'm intrigued by the suffix "G". I'm familiar with:
"F" numbers-only dial
"L" dial with letters as well as numbers
"R" inclusion of earth recall
plus a couple of more obscure variations such as "S" and "T", but not "G".

I think 'G' denotes 4000R bell coils for use on what was then the modern plug and socket system with bells wired in parallel.

Isn't that what the "8" prefix means?

Wasn't it "Dial 'M' for Murder"?

Scroll down to the end of the text.

These telephones were introduced long after All Figure Numbers (AFN) so F for figures and L for letters were no longer applicable.

The devil is in the detail, Dave, and outlined on the 'N'-drawing. All the '8' means is that it's a plug-and-socket telephone. The suffix 'G' means it has a 4k bell-movement in it.

I got caught out like that once.
