@@Hjorleifur You have a lot of it in Sweden and Norway. And I don't know myself because the Mf 35 seemed to me to have only 3 cylinder perkins. And I thought Mf 35 and Mf 135 only had 3 cylinder perkins. These perkins are known to us because they were in the Polish Ursus license. However, I want to buy such an Mf and I can see in the picture after the gearbox that it is the same as in the Mf 130. But the guy says it's a My 35 with a 4 cylinder Perkins. And one more question, you don't know if the Mf 130 MF 30 gearboxes can be fitted with a Perkins 3-cylinder engine if necessary?
