Interesting BUT in these photos, the Autoblinda Italian built armoured cars, still clad with the remains of armour, the is engine clearly visible and it can be seen to be a fixed head (Head and block cast as one), which was fitted to early 1Z's built from 1915 until 1920 using engines like that in the Theta. Both the early 1Z and Theta had the gear and hand brake levers mounted on the right hand side of the chassis.
When the Kappa was introduced in 1919, the main changes were the fitting of an engine with a detachable cylinder head and a gearbox with gear and brake levers mounted directly on top of it, and these features were carried into a 'new' 1Z and these can be clearly seen on this chassis for sale. As it was not until 1922 or 23 that the Greek letter names were allocated to chassis built earlier, I suspect that the 1Z nomenclature continued to be used for this modified chassis, the Triota name being used from 1922/3 on. These 'Triota' chassis, clad locally with armour, were used in Northern Ireland during the 'Troubles' and for some year after - the last ones were sold out of service only in the 1960's or '70's.
I feel sure that this chassis is one of these latter.
