Next UCW MkIII project

[Lynn Eades]

Hi Adam and welcome to the forum!
I assume that this is a British MkIII carrier (the bed rails tell me it is British)
British carriers had the (brass/ bronze/ gun metal?) ID plate with its TL number (stamped into the plate), riveted to the right front guard. This is your only positive identifyer for a British carrier, unless you can find the T number painted on the hull sides.
British MkIII carriers are not common among carriers, so your is a bit rare.
Assuming it is not an AOP, The only batch of Mk.III Universals was built by Ford (Dagenham- London) and the T number range was T331701 to T334900. Apart from that batch of 3200 carriers, all the other MkIIIs appear to have been Armoured OPs.
This info from Nigel Watsons "Universal Carriers" Vol I.

Your last picture shows a mortar carrier.
