Well I'd never even heard of the Indian Pattern Carrier before. Fascinating vehicle and history it turns out. Will have to add that and the Matador to my Western Desert collection. Possibly the RR A/C as well, but we'll see. I agree, there's something about that model that doesn't look quite right, but it may just be the photos...
At present the 5.5" gun, Indian Pattern carrier and RR A/C are available on the Perry site, but the Matador isn't yet.
The 17pdr meanwhile is a Blitzkrieg Miniatures model, not a Perry product... So it's under the Blitzkrieg listing on the Perry site - not with the rest of the Perry WW2 British kit.
All a tad confusing
