Ok, now found a pic of older Potain 506, version B4 with double ties. Maybe the only B4 ever seen in Finland. This pic is taken in Kokkola, August 1975 by Mr. Gronroos, (thank you Matti...)
First pic shows the load table: 750 kg / 25 m - 1000 kg / 20 m - 2000 kg / 10 m.
Lowest operating temperature -25 degrees Centigrade.
