1. The Leyland Retriever L 4144443 has the contract number on it which is unusual..V.3350?? However the Census List says that it is one of a batch L 4144434 to 4144683 to V.3740, 'Lorry 3-ton 6 x 4 Armoured Comd.'. Can anyone read the contract number better than I please? V.3330 was for Searchlight lorries, L 3910369 to 3912446 as was V.3380, L 4166193 to 4166245 but at this juncture I cannot find a V.3350.
2. The other Retriever is marked up as one of the batch H? 4580766 to 4580826 for a V.4126 'Machinery' lorry. The rego is 1947 Buckinghamshire.
3. I cannot read the Census Number of the mystery lorry either! It could be a Crossley IGL8. This is one posted previously
4. The last photo is one I published in VINTAGE ROADSCENE, and is believed to be a Karrier FM6 3-tonner circa 1934, with winch and for bodying as a breakdown lorry for India.
However, as regards 3. and 4. I am no expert and seek those who should know out, and blame them when it goes wrong!
