Daniel, Thanks for the explanation. That is really great! you have filled in all of the "grey" areas for me. What you say about the primer shroud and the German market now makes sense! I have seen the shroud on trucks built by Clark in Mulheim in the past and currently see the same on Toyota from Ansenise France. But product built in Italy (BT Cesab) has no shroud. We buy parts from HKL and find them very helpfull, but they could not answer my question anywhere near as well as you have done. Dave
