Hi, Chris. Interesting...
The size and shape are exactly right for Sherdley/ Ravenhead slim jims. I've never seen any with a gold rim before, and the books imply that this feature was unique to the top-of-the-range gaytime shape - but that's not to say they don't exist.
The other question mark I have is the flower motif - most of the flower designs I've seen are quite stylised, whereas this looks more naturalistic, and in general the Sherdley/ Ravenhead designs tend to cover the whole glass. But I'm still quite new to collecting these glasses and there is quite a lot of stylistic variation over the 16-18 years they were produced, so I'm still constantly being surprised...
