Met specials + Ayrshire cons + Birmingham?

[billy4294]

Thought I'd post these for general interest and opinions on two items (Ayrshire & Birmingham) The Lavender specials is a good photo with different ranks shown along with division letter V (Wandsworth) 3 District on collars. Standard cap badge to the MSC and LS 1914 Breast badge/Medal, all still obtainable for £10-£12, though there are some sellers on ebay (and some dealers) who charge a lot more. I bought the Ayrshire constabulary one (chromed) purely because I like the design of the badge. Anyone have any idea what period it was in use for? Obviously it is pre-53, and I have seen it on a site described as in use between about 1925 and 1936. But I have also come across early 1950's photo's showing the same style badge being worn by constables, so maybe the badge was worn as shown in my post for a great many years?
I think the Birmingham badge may be a fake? I have only ever seen one other with a pin back like this, which had a rubbed J.R. Gaunt London maker mark on it. I'm not too keen on the enamel either.
Hope you like the post, gents
Awaiting opinions
