I'm pretty sure it's Crown. Would it be possible to take a photo of the bowl from above, on a white background, preferable showing that chip as well? With the chip, if you hold it to the light and look through it to the inside of the bowl, is the glass clear or blue?
The Australian pattern (known often as 'six swirl') appears in amber, lettuce green, pastel green and has been found in citron. They first made the moulds in 1937. There are no catalogues in public hands whic show this pattern, but they definitely made the moulds.
It can have the following surface treatments: all over satin glass, textured frit between the panels, and enamel. Usually the enamel is ground from the base, but this isn't obligatory.
Here is my satin amber bowl. I think it's a rose bowl, as it often comes with the standard Crown flower block (not shown).http://i70.photobucket.com/albums/i120/retro_spection/sixswirl001.jpg
I believe it's Crown because those rose bowls are often found with the coloured enamel surfaces. I'll show an example of the enamel surface later.
A salad bowl in the same pattern, undoubtedly Crown.http://i70.photobucket.com/albums/i120/retro_spection/sixswirl008.jpg
Here's the matching nappy, with the Crown paper label:http://i70.photobucket.com/albums/i120/retro_spection/sixswirl007.jpghttp://i70.photobucket.com/albums/i120/retro_spection/sixswirl006.jpg
Same shape nappy, with the characteristic frit application between the panels:http://i70.photobucket.com/albums/i120/retro_spection/sixswirl004.jpg
Here's the nappy flattened into a small side plate. It's very wonky. This was never terribly successful and I'm astounded they didn't melt them all down.http://i70.photobucket.com/albums/i120/retro_spection/sixswirl003.jpg
Now, here's another nappy, again in clear, with the enamel surface and part ground feet:http://i70.photobucket.com/albums/i120/retro_spection/sixswirl005.jpg
See the white spots where the enamel has been ground off. This is very characteristic of this Australian treatment. You can tell Crown were pretty confident in their monopoly here :lol: :lol:
Next is a bowl, possibly intended as either a fruit or a float bowl. I think this is Crown, on the basis that it appears in all the typical surfaces and colours, and has the partially ground feet.http://i70.photobucket.com/albums/i120/retro_spection/sixswirl009.jpghttp://i70.photobucket.com/albums/i120/retro_spection/sixswirl010.jpg
Okay, now here's one I don't think is Crown. It is much more even, the glass is finer, the questionmark panels are more curvaceous, the shape looks more like those in the Walther catalogues, and the feet are more completely ground.http://i70.photobucket.com/albums/i120/retro_spection/sixswirl011.jpghttp://i70.photobucket.com/albums/i120/retro_spection/sixswirl013.jpg
Compare the feet with the ones on the first piece shown, the rose bowl:http://i70.photobucket.com/albums/i120/retro_spection/sixswirl014.jpg
I don't know whether you can see, but the ground patches on the feet are rounded on the Crown item, but rectangular on the non-Crown. (I'm hesitant to say Walther because I don't know enough about Waltherglas).
Sorry about heaving all that on you, but this is a pattern I know well.
