CMP dates
 

Iam a modeller in 1/35th scale & wondered if anybody can tell me where I can get the information as regards the first date of issue of each type of CMP vehicle? I base my models in North Africa & to a lesser extent Sicily & Southern Italy so the cutoff point for me is late 1943 Early 44 before all vehicles were painted British olive drab. I am using the excellent Mirror Models kits to make these vehicles but when it comes to the number 13 cab I can't tell when the various types came into use. The forthcoming kits are a dump truck, a 6pdr gun portee, although that one is easier as they stopped using them, a Holmes recovery unit with jibs, a 3ton petrol tanker, & a number of others mentioned for next year.
Any help would be appreciated TIA.
