The 'Universal Carrier' was only introduced in 1940, but the Scout, Machinegun and Cavalry carriers came in around '36 iirc. These were similar but did not have the box body of the Universal. I believe that there weren't even any Universals in France in 1940, although I wouldn't be prepared to put money down to back that belief.
I think Army Group North make the Mk. Is, at least the first two types anyway.
The Carden-Loyd 'tankette' was used more as an infantry support weapons carrier than a scout vehicle, although it was used as such in the RTR for a time, alongside the Vickers Mediums up to around 1938 at the latest, although I expect most would have been retired by that point.
