1/144 Airport Service Vehicle Sets 1 & 2 - Eastern Express
I don't have too much information at the moment, but it would appear that Eastern Express are planning to release two sets of Airport Support Vehicles based upon the Zil-130 chassis.
They are plastic injection, with options on clear or solid glazing (with window decals - which is in common with a lot of airliner kits).
