This cab was a joint design between Leyland and Renault, Volvo own most of Renault and needed a new cab for it's FL chassis and to save money they used this cab.
As John has stated the cab was designed as a collaboration between leyland/daf and Renault with valve as a shareholder in Renault adopting it fairly early on in its life, it reminds me of the old motor panels cab used by numerous manufacturers including foden, scammell, erf, argyll, ftf to name but a few, this cab has been bought off the shelf by several specialist manufacturers to keep costs down.
Rába's trucks originally used cabins supplied by West German MAN, but from 1980 on DAF's F241 cabin was used.[4] A few Roman cabs (of MAN origins) were also supplied from Romania in return for engines.[5] Rába's engine mainstay was itself of MAN origins, with the old D21 inline-six diesel massaged up to 300 PS (221 kW) with the help of turbocharging and intercooling.[4]
In the 1980s, Rába built no more than about 2, 000 trucks per year, although it was Hungary's third biggest employer. Being an important provider to Hungarocamion, a publicly operated international trucking firm, helped raise their international profile.[4] In 1985, Rába's business mostly consisted of engine and axle manufacturing, with only 15% of turnover being represented by trucks. Of these trucks, however, nearly 90 per cent were exported, with the lion's share going to Yugoslavia.[5] In 1986, Rába introduced a more powerful, 370 PS (272 kW) diesel engine (D11TLL) in order to help their trucks compete internationally and to meet Hungarocamion's needs. The new engine range was loosely based on the earlier MAN units, but were now of 11.05 litres, and were developed together with the Linz Institute of Graz, Austria.so its an independant hungarian company that buys cabs and componenets in but designs its own engines based on older designes, it mostly builds military chassis with M.A.N cabs and municipal chassis the leyland/daf cab
