I am need of advice for Contarex lenses specifically need to know if it is possible to "free up" ;

1) 135mm f4 Sonnar with totally jammed focusing ring .

2) 35mm f4 Distagon with totally jammed focusing ring.

Three other Contarex lenses ie 21mm Biogon , 50mm Planar and 85mm Sonnar have all been serviced and lens elements repolished and recoated but the lab. would not service the 135mm and 35mm because the focusing was seized. I can dump them - but prefer to try and free them. I have tried flushing with lighter fluid (petrol) but so far they are still jammed. Any ideas as to how they might be freed?
