Anyone see this style of coving/cornice since? The best way that I can describe it is that it is...

The best way that I can describe it is that it is a stylised oyster shell with two crossed laurel leaves on any side (they definitely aren't acanthus leaves/oak leaves/grape vine leaves). The lower third of the 'oyster shell' has a fleur de lys surrounded by it.

The property dates from 1897 - so Victorian. However, research tends to suggest that this style wasn't fancy - especially in the type of property (an upstairs flat!). Could it have be put up in the Art Deco period?

Any suggestions as to the heading of the pattern would be appreciated. (I can't get a clothed photo of it to post - partly because it is covered in layer of paint and we've only managed to see the detail on small section of it).

Thanks for your help.

Answers:    Best and easiest thing to do is look for a website on google, of which here will be ample, and look for

"plaster coving" or "plaster cornice"

You will find many websites selling plaster coving moudings of which you will be able to look though and possibly find yours.

We use them at work for matching with existing coving already surrounded by a house just like yours.

hope this help
