Die Cast Vehicle for 15mm

I have only gotten a few die cast models for my 15mm Forces as I found it more cost effective to buy Lots of vehicle of e-Bay & have found most of the lots for Die-Cast are a mixed bag with lots of different vehicles.  As I have tried to get Multiple vehicles of the same Type for gaming use I have very few Die Cast models.  The Bradleys are Matchbox, the Sheridans & M60s are Zylmex Tanks.  The Salidin wheeled armored cars are from Play Art, I don't know who makes the ambulance & the rest are Corgy.
