Volvo 480 Club Europe

Where to buy a new brake accumulator? Volvo doesnt sell them anymore. Does anyone have data of pressure an volume? Maybe could be able to find something similar then..

Seem to have found a used one. Unfortunatly there is no guarante its i better shape. Also, they are not possible to refill (without doubtful modifications), but if one could find out the pressure and volume of the origina unit, it would be easy to replace it with new, industrial accumulators.
