Weathercock appears in a Ravenhead advert David sent me dated December 1964, just at the time production was moved from Sherdley to Ravenhead.
I don't know the pattern name for the swirly conicals, but they're definitely Ravenhead. The packaging I've seen them in is a pinky-purple carrypack, which is different to the pale green carrypack that appears in the 1964 ads. So I think they must be a later design. The colours and pattern look a bit 70s to me.
The Diamante pattern appears in a Ravenhead advert launching the new chunkie shape - I think also in 1964. I have a theory (can't remember if I've mentioned it here before - apologies if I have) that the chunkie replaced the (barrel-shaped) chubbie shape. But that's only a hypothesis, just waiting to be knocked down - so if anyone has any examples of chubbies in Ravenhead packaging, I'd be very interested.
As far as I know, all the screen-printed designs were by AHW. According to McConnell, the conical was an existing Sherdley shape, but all the other shapes were designed by AHW.
Would love to see your other designs, Max - and anyone else who's got any. I'm trying to piece together as many as I can. And likewise, I MUST get to grips with my digital camera, so I can post some images of the designs I have - at the moment I only have images from e-bay sellers that I can't post here (at least I don't think I can - any copyright lawyers out there?) but could e-mail on a personal basis if anyone's interested.
