Help dating a pattern


Hi everyone. I've just received this lovely pattern in a bulk buy, and I'm trying to date it as well as get a little more information on Weldon's patterns, as I've never come across them before.

I've managed to get a little information and I'm guessing that this pattern may have been part of a Weldon's Ladies' Journal (but that's just an uneducated guess), so anything else you can add would be appreciated!

Thanks all!
Angela
