Topic: Symbol on ashtray

[Ivo]

This symbol found on a Leerdam ashtray. What does it mean?

[chopin-liszt]

Don't put your cigarettes out under the table? 
(sorry, being silly.)

I suspect that if you don't know then there's little chance of us having the answer  ............     can't see this on either your own handiwork from the 'abel/leermark' site from few years back, or on the Great Glass location.

Assume there is a paper label or whatever, from which you know this is a Leerdam ashtray?           What in  your opinion is the age of this piece Ivo?

the only silly saying I know is.........    'don't smoke in bed or the ashes on the floor may be your own'

It is a sandblasted decoration on a Copier ashtray first produced  1922 and the owner would like to know for whom it was made - are these runes? Ksi Chi? Company logo? I was thinking, you might have seen it somewhere...

[Paul S.]

who knows?  -  somehow I think that runic alphabets and latin into greek or vice versa is perhaps reading a bit too much into this symbol  -  looking at related acid etched marks for a similar time period for Leerdam - shown in your 'nl/abel/leerdam' notes - I'm not getting the impression those were created using cryptic borrowings from other alphabets...............    just my opinion of course.

My knowledge of Leerdam symbols and marks is virtually non-existent, but surprised to hear that a symbol on a piece from such a well-known and documented output should remain a mystery, still.
But hey, if it wasn't a mystery, you'd have nothing to worry your mind with            you know we'd love to help you if we could

It is not a factory mark ...

I don't know if this is any help but it does resemble the hourglass part of the logo for Longines I think.

[Ivo]

Genius, sheer genius. Makes perfect sense, thank you.

Does the Longines mark have the cross bar through its centre though?

[sayitslowly]

I sure don't know but I did find a few examples that seem to show a line in the center such as this one.
