3615 ashtray ? (on tm)

I know it says a University of Canterbury, but could this be the "Three Clip Ashtray Intercontinental"? It has three clips and looks like it could be the right time (7/11/67).

Yes I often wonder if this is the 3613 shape ashtray, but we need to find one in the Hotel Intercontinental pattern to confirm this Jeremy. Keep looking

Intercontinental Pattern, Supervitrified & 3 clips...would this be it?

This is the only Intercontinental Ashtray that I've seen. However the Portage have this shape as 1614 and we already have that ashtray shape as 1614

Next though is the 8639 which is the same as the old 1614

The earthenware 1614 is a 1210 and then became the 8042 .... though I've yet to see an earthenware ashtray in this shape.

So please come back with your thoughts Kat as we are swimming in the dark here

Keep looking for another shape in this Intercontinental pattern.

Yes I guess you are right and I can't use your photo for the 8639 as these were produced after 1981 by the looks and I'm not sure if the Intercontinental was still around then..... does anyone know?
